“This I recall to my mind, therefore have I hope. It is of the LORD’S mercies that we are not consumed, because his compassions fail not. They are new every morning: great is thy faithfulness.” (Lamentations 3:21-23)
Even when his people were in the midst of reaping the severest consequences for their sin, Jeremiah upheld himself with the remembrance of God’s mercy and faithfulness. David invited the chastening of God upon his life, and yet, even when the rod was upon him, he looked to his God for deliverance. Sin has consequences, but the Lord’s mercies are new every morning. David saw his sin, but he also believed that God’s mercy and grace could be greater than his sin.
“Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions. Wash me throughly from mine iniquity, and cleanse me from my sin. For I acknowledge my transgressions: and my sin is ever before me.” (Psalm 51:1-3)
What we know of God must be what He has revealed of Himself in His Word. Paul advised that we behold both the goodness and severity of God. (Rom. 11:22) Our glory is knowing and understanding the Lord who is a God of mercy and judgment. (Jer. 9:24)
Yes, there are times when we are not faithful. God does not wink at our sin. But no matter how low our folly brings us, the God of mercy remains. He is faithful to forgive, cleanse, and continue to help those who cry out to Him for mercy. He cannot deny Himself.
