Having confessed his sinfulness and rebellion against God, David continues to fall upon the mercy of God now in supplication – asking the God would purge him from his iniquity and cleanse him from all unrighteousness. But why does David so desperately seek forgiveness? Why does he repeatedly entreat God to wash him, to create in him a clean heart, to renew and restore him? Far from being driven simply by fear of punishment and God’s wrath, David fears losing something infinitely more valuable of which he should rightfully be deprived for all eternity: the fullness of joy found in the presence of God (Ps. 16:11). In this sermon, Pastor Matt preaches on the significance of David’s plea for God to restore to him the joy of salvation (Ps. 51:8, 12) and explains precisely what this forgiveness would end up costing God himself.
