Stott on election

Let no one say that the doctrine of election by the sovereign will and mercy of God, mysterious as it is, makes neither evangelism or faith unnecessary. The opposite is the case. It is only because of God's gracious will to save that evangelism has any hope of success and faith becomes possible. The preaching of the gospel is the very means that God has appointed by which he delivers from blindness and bondage those whom he chose in Christ before the foundation of the world, sets them free to believe in Jesus, and so causes his will to be done.
