The 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 DeverThe church arises only from the gospel. And a distorted church usually coincides with a distorted gospel.
Mark DeverAs long as quick numerical growth remains the primary indicator of church health, the truth will be compromised. Instead, churches must once again begin measuring success not in terms of numbers but in terms of fidelity to the Scriptures.
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 DeverWe should want to evangelize because of the joy that God puts in our hearts. Ultimately, that's the best reason for sharing our faith.
