The gospel has two parts. It has the part that says you're a sinner, and it has the part that says you're loved and accepted.
Timothy KellerTo 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 KellerAll change comes from deepening your understanding of the salvation of Christ and living out the changes that understanding creates in your heart.
