Charles H. Spurgeon on Psalms 130:1

Have I cried. There are many kinds and degrees of prayer in the world; from the coldest form to the most intense agony. Every one prays; but very few "cry." But of those who do "cry to God", the majority would say, —"I owe it to the depths. I learnt it there. I often prayed before; but never —till I was carried down very deep —did I cry." "Out of the depths have I cried unto thee, O Lord." It is well worth while to go down into any "depth" to be taught to "cry." It is not too much to say that we do not know what prayer may be till we have "cried." And we seldom rise till we have gone very deep. "I die! I perish! I am lost! Help, Lord! Help me! Save me now! Do it now, Lord, or I am lost. O Lord, hear! O Lord, forgive! O Lord, hearken and do; defer not, for thine own sake, O my God!" In mid day, if you are taken from the bright and sunny scenes of light, and go down into the bottom of a pit you may see the stars, which were invisible to you in the upper air. And how many could say that things they knew not in life's noon, they have found in life's midnight, and that they owe their glimpses of glory, and their best avenues of thought, and the importunacy of prayer, and the victories of faith, to seasons when they walked in very dark places. "Out of the depths have I cried unto thee, O Lord." —James Vaughan.
