Testimonies 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 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 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 DeverI want to defend the right of employees to share the gospel in appropriate situations. Every situation requires wisdom and insight. I don't think it's wise to say, "Share the gospel every time you can". I can see all kinds of problems that come from that approach.
Mark DeverA healthy church is not a church that's perfect and without sin. It has not figured everything out. Rather, it's a church that continually strives to take God's side in the battle against the ungodly desires and deceits of the world, our flesh, and the devil. It's a church that continually seeks to conform itself to God's Word.
