To preach the gospel is to show people their need for salvation against a backdrop of God's nature and the character of sin, and then present Jesus as the only remedy for what ails them and the world. In my weekly preaching in the worship services I always call people to believe in Christ.
Timothy KellerJesus Christ, who had all the power in the world, saw us enslaved by the very things we thought would free us ... He laid aside the infinities and immensities of His being and, at the cost of His life, paid the debt for our sins, purchasing us the only place our hearts can rest, in His Father's house. Knowing He did this will transform us from the inside out.
Timothy KellerThe Gospel does not promise you better life circumstances; it promises you a better life.
