What is the gospel to people who are saved?

Les teaches that to us who are saved, the gospel, the preaching of the cross, is not just a ticket to Heaven—it is the power of God. He contrasts this with Reformers and good-works people who insist we must earn our way into Heaven, saying there is nothing we can do but take what God has offered. The preaching of Christ crucified is a stumbling block to the Jews and foolishness to the Greeks, but to those who are called, both Jews and Greeks, Christ is the power of God and the wisdom of God. That power is extraneous to anything human, a power man cannot even begin to touch.
