I think that there are many things in the New Testament that show us that the godliness of our conversation plays an important evangelistic role. The apostles are clear that we mustn't limit the explicit sharing of the gospel to formal preaching. It can also happen in ordinary conversations.
Mark DeverI do want to pray for the Lord to glorify himself and, yes, I also will pray for an outpouring of his Spirit, but I also will rejoice in what he is doing now, and I will try to be a faithful steward of the gospel by preaching it "in season and out of season", as Paul reminds us. So I want to be careful not to make an idol out of revival, or to rely upon it to the point where I don't plan for evangelism.
Mark DeverThere is simply so much reason to believe the good news of Jesus Christ in history, in Scripture, as well as in our own experience that it would take a leap of faith not to believe in the gospel.
Mark DeverMy task as a pastor is to remind people of the need for balance. If someone wants to stress personal union with Christ, I remind them of the need for knowledge as well. If they want to stress knowledge, I tell them about their need to depend on Christ.
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.
