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 KellerThe Christian Gospel is that I am so flawed that Jesus had to die for me, yet I am so loved and valued that Jesus was glad to die for me. This leads to deep humility and deep confidence at the same time. It undermines both swaggering and sniveling. I cannot feel superior to anyone, and yet I have nothing to prove to anyone. I do not think more of myself nor less of myself. Instead, I think of myself less.
Timothy KellerThere is a joy available that the deepest grief cannot put out. No circumstance or person can take away the joy God gives.
