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 DeverWe mustn't be content to just sit around pointing out the errors in others; we actually need to be sharing the gospel and praying for people to be converted.
Mark DeverI love Iain Murray's definition of worldliness: towards the end of Evangelicalism Divided, he says that worldliness consists of loving idols and being at war with God. I think that's true in the lives of too many professing Christians today.
Mark DeverIf you think that the gospel is all about what we can do, that the practice of it is optional, and that conversion is simply something that anyone can choose at any time, then I'm concerned that you'll think of evangelism as nothing more than a sales job where the prospect is to be won over to sign on the dotted line by praying a prayer, followed by an assurance that he is the proud owner of salvation.
Mark DeverI heard about a pastor in a church of 5,000 people who employed two seminary students whose main responsibility was to get four new people baptized each week. When asked, "What happens if they can't meet the quota?", his response was, "Then I'll find two students who can". This man wasn't even remotely interested in true gospel preaching. He was results-driven.
