God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)
So far from making evangelism pointless, the sovereignty of God in grace is the one thing that prevents evangelism from being pointless. For it creates the possibility – indeed, the certainty – that evangelism will be fruitful. Apart from it, there is not even a possibility of evangelism being fruitful. Were it not for the sovereign grace of God, evangelism would be the most futile and useless enterprise that the world has ever seen, and there would be no more complete waste of time under the sun than to preach the Christian gospel.
