Adam Clarke on Psalms 32:6

For this shall every one that is godly - Because thou art merciful; because thou hast shown mercy to all who have truly turned to thee, and believed in thee; every one who fears thee, and hears of this, shall pray unto thee in an acceptable time, when thou mayest be found; in the time of finding. When the heart is softened and the conscience alarmed, that is a time of finding. God is ever ready; men are not so. Who can pray with a hard heart and a dark mind? While you feel relentings, pray.

Surely in the floods - In violent trials, afflictions, and temptations; when the rains descend, the winds blow, and the floods beat against that godly man who prays and trusts in God; "they shall not come nigh him," so as to weaken his confidence or destroy his soul. His house is founded on a rock.
