Then I acknowledged my sin to you and did not cover up my iniquity. I said, “I will confess my transgressions to the Lord”—and you forgave the guilt of my sin. Psalm 32:5, NIV
SUPPOSE YOU WERE walking down your street and a friend of yours suddenly burst out of his house and deliberately knocked you down on the sidewalk. Now suppose that friend said to you, “Hey, it wasn’t my fault. You would’ve done the same thing if you’d had the chance.” How would you feel hearing that sort of thing? You’d be angry, right?
OK, suppose the friend said instead, “I didn’t mean anything by it.” How would you feel then? Would you be satisfied with that?
More than likely you wouldn’t be satisfied, right?
God doesn’t want us to say such things when we make a mistake or do something wrong. Why? Because none of those phrases contains the two necessary ingredients of repentance. Do you know what those two necessary ingredients of repentance are? Confession and apology.
