Unfortunately, many of our churches calibrate their life to these nominal Christians. The predictable result is that you get fake, hypocritical churches that confuse the message of the gospel and make it hard for others who are trying to do genuine evangelism.
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 DeverAccording to the New Testament, the church is primarily a body of people who profess and give evidence that they have been saved by God's grace alone, for His glory alone, through faith alone, in Christ alone.
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.
