Every 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.
Mark DeverIt'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 DeverDo you want to know that your new life is real? Commit yourself to a local group of saved sinners. Try to love them. Donโt just do it for three weeks. Donโt just do it for six months. Do it for years. And I think youโll find out, and others will, too, whether or not you love God. The truth will show itself
Mark DeverIf you are not a member of the church you regularly attend, you may well be going to hell.
Mark DeverThere is no gospel without the offence. This is God's wisdom. It never seems sensible to us in our flesh.
