Men must be told that they are dead, and that only the Holy Spirit can quicken them; that the Spirit works according to his own good pleasure, and that no man can claim his visitations or deserve his aid. This is thought to be very discouraging teaching, and it is, but men need to be discouraged when they are seeking salvation in a wrong manner. To put them out of conceit of their own abilities is a great help toward bringing them to look out of self to another, even the Lord Jesus. The doctrine of election and other great truths which declare salvation to be all of grace, and to be not the right of the creature, but the gift of the Sovereign Lord, are all calculated to hide pride from man, and so to prepare him to receive the mercy of God.
Charles Spurgeon quoted from The Baptists, Vol. 3 by Tom Nettles, p. 335
