This [temptation/affliction] the Lord does in great wisdom for the good of His children: first to teach them, that no man is able of himself to carry himself in any acceptable course of his calling without God’s special assistance and grace. Secondly, to stir up in them those good gifts and graces which He has formerly bestowed on them; as the fear of His name, the love of His majesty, the gifts of prayer, faith, patience, and many other which He would have tried in the entrance of their callings, and exercised in the continuance therein unto the end.
William Perkins (Theologian, 1558 – 1602)
