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 KellerWhen we grasp that we are unworthy sinners saved by an infinitely costly grace, it destroys both our self-righteousn ess and our need to ridicule others.
