I have heard people preach this way: “The good news is that God is healing and will heal the world of all its hurts; therefore, the work of the gospel is to work for justice and peace in the world.” The danger in this line of thought is that the good news becomes a divine rehabilitation program for the world, rather than an accomplished substitutionary work. “Believing the good news” means joining that program, rather than receiving Christ’s finished work.

In other words, the gospel becomes primarily a salvation by practice instead of a salvation by faith. As J. I. Packer says, “The gospel does bring us solutions to these problems, but it does so by first solving…the deepest of all human problems, the problem of man’s relation with his Maker; … and unless we make it plain that the solution of these former problems depends on the settling of this latter one, we are misrepresenting the message and becoming false witnesses of God. –Tim Keller

What shocked me here is the sentence “good news (gospel) becomes a divine rehabilitation program for the world.”—That is pretty shocking and I feel guilty that to some measure we, evangelicals, charismatics, are guilty. And that’s precisely what diminished the power of the gospel or the word of God in our lives because we misrepresent the gospel. We preach a gospel that’s cheap. We want to stress the divine healing. Or we say “Come to Christ, and you will be blessed with healings, eternal life etc”. This is true, but the emphasis is not reflecting the real gospel. The true gospel is to resolve the deepest of all human problems, the problem of man’s relation with his Maker. Only then through this, we can see solution to all the problems of hurts, brokenness that we face in the world.
Very powerfully stated, we can be misrepresenting the gospel and becoming false witnesses of God.
