The Works of God

J.I. Packer on grace:

Grace is God drawing us sinners closer and closer to himself.

How does God in grace prosecute this purpose? Not by shielding us from assault by the world, the flesh and the devil, nor by protecting us from burdensome and frustrating circumstances, nor yet by shielding us from troubles created by our own temperament and psychology; but rather by exposing us to all these things, so as to overwhelm us with a sense of our own inadequacy, and to drive us to cling to him more closely.  This is the ultimate reason, from our standpoint, why God fills our lives with troubles and perplexities of one sort and another: it is to ensure that we shall learn to hold him fast. The reason why the Bible spends so much of its time reiterating that God is a strong rock, a firm defense, and a sure refuge and help for the weak, is that God spends so much of his time bringing home to us that we are weak, both mentally and morally, and dare not trust ourselves to find or to follow, the right road.
