Let’s not believe that we are simply all engaged in some search for truth. The fall did not leave people neutral toward God but at enmity with him. Therefore we must not pretend that non-Christians are seekers by the simple virtue of their having been made in the image of God. The Bible teaches that people are by nature estranged from God, and we must be honest about that.
What is repentance? It is turning from the sins you love to the holy God you’re called to love. It is admitting that you’re not God. It is beginning to value Jesus more than your immediate pleasure. It is giving up those things the Bible calls sin and leaving them to follow Jesus.
When we tell the gospel to people, we need to do it with honesty. To hold back important and unpalatable parts of the truth is to begin to manipulate and to try to sell a false bill of goods to the person with whom we are sharing. So however we evangelize, we aren’t to hide problems, to ignore our own shortcomings, or to deny difficulties. And we are not to put forward only positives that we imagine our non-Christian friends presently value and present God as simply the means by which they can meet or achieve their own ends. We must be honest.
