There 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 DeverLet's say that you want to do everything out of the joy that comes from knowing the Lord. Well, a lot of people aren't built like that emotionally. If they think that some sort of feeling is the basis for their action, they are going to feel justified sitting around, although they are going to feel bad that they have never taken one step of obedience because their heart is cold.
Mark DeverThe difference between apologetics and evangelism is that in apologetics, you are answering objections that the world raises, whereas in evangelism, you are bringing the message that Christ brought. So unbelievers tend to set the agenda in apologetics, and you set the agenda in evangelism.
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 DeverAll evangelists want to do is share a message about the forgiveness of sins and reconciliation with God. But our world is confused by the confidence we have in the gospel, and is threatened by it. Satan, I am sure, causes those things to echo in the world to increase this sort of common confusion.
