Let it slide?

Heidelberg Catechism
Q & A 10
Q. Will God permit
such disobedience and rebellion
to go unpunished?

A. Certainly not.
He is terribly angry
about the sin we are born with
as well as the sins we personally commit.

As a just judge
he punishes them now and in eternity.¹
He has declared:
“Cursed is everyone who does not continue to do
everything written in the Book of the Law.”²

Note: mouse over footnote for Scripture references.

God will not let sin slide, because he cannot; it would be unjust, it would be against his nature, it would be wrong, and it would be inherently contradictory. At its core, sin is the assertion of our own self-will against God’s will in a declaration of mistrust: it is the insistence that God neither knows nor truly cares what is best for us, and that we’re better off going our own way. That is a defiant falsehood in the eye of the one who is Truth, a falsehood straight from the pit of Hell; he could not simply ignore it without ceasing to be true, nor would he be doing us anything but ill if he could. Nor, in truth, would his doing so be welcomed; having rebelled against God, why would we want him to come crawling to us to take him back?
