This Psalm must ever be, in its successive steps, the mould of the experience of a sinning saint who comes back to full communion and service. The steps are:
(1) sin thoroughly judged before God (vs. 1-6);
(2) forgiveness and cleansing through the blood (v. 7.f.c.)
(3) cleansing (v. 7,1,c, to 10.) Compare (John 13:4-10); (Ephesians 5:26); (1 John 1:9).
(4) Spirit-filled for joy and power (vs. 11,12);
(5) service (v. 13);
(6) worship (vs 14-17);
(7) the restored saint in fellowship with God, not about self, but about the blessing of Zion. Personally, it was David's pathway to restored communion after his sin with Bathsheba. Dispensationally, it will be the pathway of returning Israel. (Deuteronomy 30:1-10).
