Acts 13:44–46 (ESV)

“The next Sabbath almost the whole city gathered to hear the word of the Lord. But when the Jews saw the crowds, they were filled with jealousy and began to contradict what was spoken by Paul, reviling him. And Paul and Barnabas spoke out boldly, saying, ‘It was necessary that the word of God be spoken first to you. Since you thrust it aside and judge yourselves unworthy of eternal life, behold, we are turning to the Gentiles.’”

This passage captures a decisive moment in redemptive history — when the gospel began to move beyond Israel to the Gentile world. But why was Paul’s message so effective among the Jews in the first century, while millions of Jews today, even in a city like New York, remain unmoved by the same gospel?

Let’s look at six key observations that shed light on this question.

1. A Message Spoken into Expectation

In Paul’s day, the Jewish people lived under Roman rule, weary and longing for deliverance. They were hungry for redemption, holding onto the promises of God made through Abraham and David. Every Sabbath they heard the prophets read aloud; their hearts burned with anticipation that God would soon act.

When Paul preached Jesus as the promised Messiah — crucified, risen, and reigning — his message met that expectation. He wasn’t introducing a foreign religion but revealing the fulfillment of their deepest hope.

Today, however, that sense of spiritual longing is often absent. Our modern world — Jewish and Gentile alike — is not waiting for redemption but for comfort, security, and success. Paul could proclaim, “The Messiah has come!” to people who were waiting for Him. Today, we often must begin one step earlier — by showing why humanity needs a Messiah at all.

That’s the challenge of our time: to awaken a thirst that has gone dry.

2. The Power Behind the Preaching

What made Paul’s ministry so effective wasn’t persuasive skill alone, but the power of the Holy Spirit.

“My message and my preaching were not with wise and persuasive words, but with a demonstration of the Spirit’s power.” (1 Corinthians 2:4)

The Spirit opened hearts (Acts 16:14), confirmed the message with miracles, and gave boldness to preach amid opposition.

That same power is still available today. The Holy Spirit remains the constant factor — the unchanging source of conviction, revelation, and transformation.

Yes, Paul had a unique apostolic calling, personally set apart by God. But you’re right — we need more people today who are called, set apart, and Spirit-filled for the difficult task of gospel proclamation in our secularized world. Clever communication will never replace spiritual anointing.

The early church prayed, “Lord, grant your servants to speak your word with all boldness” (Acts 4:29). We must pray the same.

3. The Mystery of Israel’s Hardening

Romans 9–11 reveals one of the deepest mysteries in Scripture: Israel’s rejection of the gospel is neither total nor final.

“A partial hardening has come upon Israel, until the fullness of the Gentiles has come in.” (Romans 11:25)

This means God’s plan is still unfolding. Israel’s blindness opened the door for the Gentiles to come in, but one day, the veil will be lifted and “all Israel will be saved” (Romans 11:26).

This mystery humbles us. It shows that salvation history is not a human strategy but a divine design. The same God who allowed Israel’s eyes to be veiled will one day unveil them again.

As Paul exclaimed at the end of Romans 11:

“Oh, the depth of the riches and wisdom and knowledge of God!”

It truly is awesome.

4. The Modern Barriers in Our Time

After the destruction of the Temple in A.D. 70, Judaism was forced to redefine itself. Without sacrifices or a temple, the faith shifted toward Torah study, rabbinic tradition, and synagogue life. This redefinition preserved Jewish identity but diminished the felt need for atonement, which Jesus came to fulfill as the perfect sacrifice.

As you insightfully noted, this shift made the gospel’s message of a “once-for-all sacrifice” seem unnecessary. Add to that the centuries of persecution done in the name of “Christianity,” and many Jewish communities understandably view the gospel with suspicion or pain.

In places like New York City, many Jews are now deeply secularized, identifying culturally rather than spiritually. They are not looking for a Messiah — nor often for any religious answer at all.

So unlike Paul’s audience, modern Jewish people aren’t wrestling with unfulfilled prophecy. They are wrestling with indifference. That’s the new mission field — one that requires both compassion and courage.

---

5. The Gospel Still Has Power

Despite all these barriers, the gospel is still as powerful in the twenty-first century as it was in the first.

“The word of God is not bound.” (2 Timothy 2:9)

The same Spirit who opened hearts in Pisidian Antioch can open hearts in Manhattan or Brooklyn today. Some Jewish men and women are coming to faith in Jesus — often through reading passages like Isaiah 53, Psalm 22, or Daniel 9, where the Spirit unveils Christ in their Scriptures.

The gospel’s power is timeless. It doesn’t need modernization; it needs Spirit-filled proclamation and lives that bear its fruit.

---

6. Our Call Today

Paul wrote that Israel’s unbelief would lead to Gentile salvation — and that the salvation of the Gentiles would one day make Israel jealous (Romans 11:11).

That’s a profound mystery: as the nations experience God’s grace, Israel will desire that same intimacy with the God of Abraham through His Messiah. How that plays out exactly, we do not know — but we trust that God’s plan is perfect.

You’re right to emphasize that while we are called to embody the grace of God, we are also commanded to proclaim it. The Great Commission (Matthew 28:18–20) is not a passive calling. “Go and make disciples” is an active command.

Living out the gospel gives our message credibility. Speaking the gospel gives it clarity. Both are essential.

We are not called merely to live attractively before Israel but to bear witness to Jesus before all nations — in word, in truth, and in love.

---

Conclusion

Paul’s message was effective in the first century because it met a people longing for redemption, and because it was empowered by the Holy Spirit.

Today, many hearts are indifferent or hardened, yet the Spirit and the gospel remain unchanged. Our task is to pray for more laborers, preach with boldness, embody grace with humility, and trust that God’s redemptive plan — for Israel and the nations — is still moving toward its glorious fulfillment in Christ.

The same God who opened the hearts of Jews and Gentiles in Acts 13 is still at work today. The gospel that turned the world upside down then still holds the power to do so now.

I love the idea that we have a divine author for the scripture and of course rightly so.

I’m only saying this to counter folks like Kaiser who, only believing the human author and the historical text, and when I read that I have an immediate reaction thinking is he even a Christian to begin with? And if anyone wants to do critical thinking, I would imagine a better subject would not be a divine book, maybe critical race theory now I suppose. There are s may critical theological scholars who love to dabble with the holy Word of God, not knowing that they are dabbling with every power of God himself. To call Bible as written by a human author, and to eliminate anything that’s of sign and wonders for their sake of human reasoning and rationale is beyond anything that’s even remotely rational on the first place. Because God cannot be rationalized, He is above reason. Even the foolishness of God (so to speak) is wiser than the wisdom of men. 1 Cor 9.

1 Corinthians 1: ²² For Jews demand signs and Greeks seek wisdom, ²³ but we preach Christ crucified, a stumbling block to Jews and folly to Gentiles, ²⁴ but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God. ²⁵ For the foolishness of God is wiser than men, and the weakness of God is stronger than men.

So why dabble with the holy word of God? I am amazed I haven’t not heard of any dabbing with Koran or the Buddhist book thus far, why? I wonder if the devil knows who is he going after?

To make the matter worse, this scholarship has produced man-made theology twisted to fit their agenda, case in point homosexuality usually be taking the case of slave, women.

Romans 1: ¹⁸ For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. ¹⁹ For what can be known about God is plain to them, because God has shown it to them.

Calling slaves of the bible is wrong, therefore the whole bible is not from God is so wrong, for instance, because the slavery of the bible is not closed, and its debt paying, while the American slavery of the past is closed (meaning you are in it for life and your children etc.), and also its not debt paying, it’s just bought. Therefore the argument via the slavery just doesn’t stand at all. The case for women, it’s actually the bible teaching that lifted women in the Roman empire days, and its Jesus who included Mary Magdalene, it’s Jesus who stopped on his way with many men following him, for the bleeding woman who was unclean. It was Jesus who wept after seeing Mary and Martha wept for their brother who was dead. It was Jesus who rebuked Simon the Pharisee who tried to stop the woman pouring her perfume on Jesus’ feet. It was Jesus who chose to appear to women first at his resurrection even before the apostle big names like Peter, James and John. So scholarship has no ground to criticize there Bible as old fashion and out of date for the women.

Twisting the holy Scriptures

To even select a divine book or at least a religious book full of God’s love, glory, passion  and interaction with his people called Bible and to call it as a human author book is a spiritual assault of the divinity of God and his hands on his book. It is inconceivable how Bible has been made to be so broad , in fact as broad as you want, in the way you interpret it to suit one’s agenda! The critical and progressive churches today love to remove the supernatural of Christ, and to remove any scriptures on his resurrection, and to impose their LBGTQ ideology upon scriptures, by bending and twisting the scriptures to fit their quest. Now it’s shocking and deeply disappointing the Church of England Anglican Archbishop of Canterbury has endorse same sex marriage with all his theological training. It tells you something, the liberal theologians have no lack of knowledge, and knowledge itself if not taught properly falls in bad hands. People need to be aware of the warning Jesus gave: Whoever take any word out of this book Bible, I will remove his lampstand form him. If anyone  add one word to the bible, he will add woe to him.

Rev 22: ¹⁸ I warn everyone who hears the words of the prophecy of this scroll: If anyone adds anything to them, God will add to that person the plagues described in this scroll. ¹⁹ And if anyone takes words away from this scroll of prophecy, God will take away from that person any share in the tree of life and in the Holy City, which are described in this scroll.

Only Divine author can prophesy the future

I love what Dr Belcher said about his exposition on David when he wrote Psalm 23:4, because there is the divine author, he understood that the Messiah will go through the valley of the shadow of death and therefore we today have the assurance of Christ as we are going through tough times and difficulties that Christ has gone thru that before us. We have therefore the assurance he will be with us and pull us through. And that is beautiful. Like professor said if we don’t have a divine author, we won’t see the connection of that Psalm 23 text for God’s people today.

If we take away the divine authorship from the Bible, what is there left for us to find God and seek God from his holy scriptures?

We might as well read out some human author best seller book on how to be a good guy or how to find happiness in life!

Psalm 1 Blessed is the one
    who does not walk in step with the wicked
² but whose delight is in the law of the Lord,
    and who meditates on his law day and night.
³ That person is like a tree planted by streams of water,
    which yields its fruit in season
and whose leaf does not wither—
    whatever they do prospers.

Psalm 1 says blessed be the man who meditates upon the Word of the Lord day and night, he shall be like a tree planted by streams of water, and bear fruits in due season. You know why is it so blessed by reading the bible and meditating it? Because the bible is life. It’s the logos, the Lord Jesus himself, and you draw life, strength, hope, joy from it. Because the author is God himself. And such divine book is no just intellectual book, but its intellectualwith LIFE in it too.

Jesus struck the man of lawlessness on his coming back by the word of his mouth. It’s the word that Jesus and the Father that created the world. Word is so powerful, and we must submit our hearts and love passionately the word of the Lord daily.

Conclusion: Loving the Word, Loving the Author

The Bible is not a museum of religious thought. It is the voice of the living God.
It speaks. It convicts. It heals.

To love the Bible is to love its Author. To submit to its truth is to submit to Christ Himself. Let us therefore treasure it, meditate on it, and defend it — for in doing so, we defend the very revelation of God to the world.
