Here is a link to Spurgeon’s Comments on Psalm 130 to which I referred in the sermon yesterday, with what I quoted directly marked in red below.   This is his exposition of Verse 1.  The rest can be found by clicking the link. I recommend taking one verse per day for reflection through this week:

Verse 1. Out of the depths have I cried unto thee, O LORD. This is the Psalmist’s statement and plea: he had never ceased to pray even when brought into the lowest state. The depths usually silence all they engulf, but they could not close the mouth of this servant of the Lord; on the contrary, it was in the abyss itself that he cried unto Jehovah. Beneath the floods prayer lived and struggled; yea, above the roar of the billows rose the cry of faith. It little matters where we are if we can pray; but prayer is never more real and acceptable than when it rises out of the worst places. Deep places beget deep devotion. Depths of earnestness are stirred by depths of tribulation. Diamonds sparkle most amid the darkness. Prayer de profundis gives to God gloria in excelsis. The more distressed we are, the more excellent is the faith which trusts bravely in the Lord, and therefore appeals to him, and to him alone. Good men may be in the depths of temporal and spiritual trouble; but good men in such cases look only to their God, and they stir themselves up to be more instant and earnest in prayer than at other times. The depth of their distress moves the depths of their being; and from the bottom of their hearts an exceeding great and bitter cry rises unto the one living and true God. David had often been in the deep, and as often had he pleaded with Jehovah, his God, in whose hand are all deep places. He prayed, and remembered that he had prayed, and pleaded that he had prayed; hoping ere long to receive an answer. It would be dreadful to look back on trouble and feel forced to own that we did not cry unto the Lord in it; but it is most comforting to know that whatever we did not do, or could not do, yet we did pray, even in our worst times. He that prays in the depth will not sink out of his depth. He that cries out of the depths shall soon sing in the heights.
