day no. 13,154: all of it imputed

Mercy does not give something bad that was earned or deserved.
Grace gives something good that was not earned or deserved.

By God's mercy, He does not treat us as our sins deserve.
He provides Jesus as our substitute.
Jesus takes our sin upon Himself.
He dies for our sins.

By God's grace, He treats us as though we've never sinned.
He provides Jesus as our substitute.
Jesus gives His righteousness to us.
He lived for our righteousness.

We are saved from our sins by His mercy.
We are sanctified through His life by His grace.
