It's fine to deal with people's doubts and explain why they have good reasons to believe in Christ. But until we tell them the good news of Jesus Christ, we haven't done our job. They need a saviour that God has provided them in Christ. Once they know that, we can do as much apologetics as we need to.
Mark DeverIf you are not a member of the church you regularly attend, you may well be going to hell.
Mark DeverThe truly changed, truly converted, truly Christian heart can say with John Newton, โI am not what I ought to be. I am not what I wish to be. I am not what I hope to be. Yet I can truly say, I am not what I once was. By the grace of God, I am what I am.
Mark DeverTestimonies are great things about what the Lord has done for us, but no-one will be offended when you talk about what God has done for you. You need to be specific about sin, about Christ's death on the cross, about others' need for a saviour, and about their need to repent and trust in Christ.
Mark DeverFrom the time of Cain until the last believer before Christ's return, we are all fundamentally in the same boat. We suffer the same spiritual afflictions and tendencies.
Mark DeverEvery believer should evangelize. I know some Christians think that evangelism is only for people with special gifts for it, but I don't believe the New Testament teaches that. While Paul does say that some believers have the call to be evangelists, all of us have the responsibility of evangelism.
