Advice on evangelism needs to be tailored to individual situations. For instance, I know someone who needs to be encouraged to speak less and work more. That would be a better testimony for him because he has certainly let his work colleagues know about Jesus. It's not that I don't want him to witness about Jesus, but I have a lot of sympathy for his employer. He is paying for work to be done.
Mark DeverEvangelism is not simply looking at someone and saying, "Look, you have to become a Christian". Instead, an evangelist tells us the truth about who God is, and explains where we stand as a result of that. People can ignore us - indeed, they have every legal right to do so.

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 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.
