If 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 DeverWhat really concerns me is for Christians to understand the fundamentals of evangelism in a way that is helpful in the contemporary scene.
Mark DeverWe can't know at any given time how God will bless our faithful witness. So the apparent numerical growth of the church is never a good guide to how faithful we have been in evangelism.
Mark DeverFor a Christian, our fears about the future are rooted in those places where our will differs from God's will.
Mark DeverAn evangelist no more imposes his views on others than a pilot imposes his views on his passengers when he lands a plane on a runway. I bet the passengers are glad!
Mark DeverWe need to be realistic and recognize that there will be times when we won't be sharing our faith out of an overwhelming sense of joy. When that happens, that's a call to look at our own devotional lives. Are we putting our hearts and minds before the Lord and under his cross everyday? Do we remind ourselves continually that we have been ransomed by the death of the Saviour? When we meditate on Christ's death for us, it doesn't mean that we never have struggles in our obedience, but it does help.
