In Psalm 106 the psalmist lists all of the many failures of the children of Israel from Egypt to Cannan. Despite all that He was doing for them, they piled up sin, failure, and complaints against God. Many times God delivered them, but they always seemed to find a way to sin.
But then comes v44-45.
“Nevertheless he regarded their affliction, when he heard their cry: and he remembered for them his covenant, and repented according to the multitude of his mercies.“
I am glad to know that His mercy is never the less. It is always the more. Never less than my sin and failures. Always more.
