St Augustine’s book of Confession is so powerfully written to demonstrate the power of desire, lust, and delight. I will write on that a lot in future.

Psalm 40:6–8 (NASB 2020)
6 You have not desired sacrifice and meal offering;
You have opened my ears;
You have not required burnt offering and sin offering.
7 Then I said, “Behold, I have come;
It is written of me in the scroll of the book.
8 “I delight to do Your will, my God;
Your Law is within my heart.”

The key thing that I want to bring up here is the word I delight to do your will O my God. This is an incredibly powerful important word. I delight, not I want to, not I will. You know we say a lot we will serve the Lord with our hearts and all this is from all mental cognitive power I will. However this is I delight to do your will.

“I delight” comes from the heart, “I will” comes from the mentor power attitude. You may not really enjoy or want to do it, but you could be saying but I will do it for whatever reason. It could be because of obligation; it could be you under compensation. By here in the Psalm 40 this is clearly talking more than just David, this is talking about the Lord Jesus Christ the son of God. He said I delight to do your will that is in NASB & ESV. In NIV, i it says I desire to do your will. Now I desire to do your will is better that I will do your will. However I desire is a step lower than I delight into your will. Do you see the difference? I desire is like I want to it, is good to do. But when I say I delight to do your will I will do it with joy. I enjoy doing it.

Christians should get to the posture of saying I delight to do your will. That means when we do God’s will, it is no more an obligation on our part as Christ followers. Other perspective is I should be doing it for the sake of obedience. All for the sake of blessings. That’s religion!

Best is I delight to do it. Whether there is compensation or blessings or not I actually really want to do it as I enjoy it. Because that is how I find so much joy doing it even if you don’t pay me I would do it, even there’s no blessings for doing that I would do it. That’s a kind of attitude. Doing it for the Lord because you are affectionate for him. You don’t need to do it for a reward, because your reward is the Lord, and that means whatever He has for you will be great! You have to trust him for everything. He is the first cause of your very existence. Can’t he not take care of you?

Col 3 ²³ Whatever you do, do your work ^[a]heartily, as for the Lord and not for people, ²⁴ knowing that it is from the Lord that you will receive the reward ^[b]of the inheritance. It is the Lord Christ whom you serve.

Realistically it’s always a mixed bag of I delight, and I desire, and even I will. The worst is you are out of all these combo. You don’t want to be in the group of “I will do my own will”. That’s a way to destruction.

But even if you have a I will , slowly, you just need to meditate and pray for the Lord to work in you, and you will birth the I desire. Eventually you move into the I delight. But even with that, things fluctuate, and you find yourself popping back and forth between them, and it’s okay. You just need to be like what Jesus said, I am the Olive, abide in me, you will bear much fruit.

Our delight in God’s will, can only come from abiding in Christ. Christ is the absolute fulfilment of all the power and blessings of God. He is the image of God, and He is God.

John 15: ⁴ Abide in me, and I in you. As the branch cannot bear fruit by itself, unless it abides in the vine, neither can you, unless you abide in me.

Abide means like a branch hang onto the Vine-and Jesus is the Vine. There is no formula as a Christian, but there is a relationship with Christ.
