I will bear the indignation of the Lord
because I have sinned against him,
until he pleads my cause
and executes judgment for me.
He will bring me out to the light;
I shall look upon his vindication.

– Micah 7:9

How long does the Lord's indignation land on us for our sin? Until our cause has been pleaded and judgment is executed on it.

Enter Christ the righteous, Christ our Advocate. He takes our judgment upon himself, and consequently the Lord's indignation. God says so through Micah.

So, because we are clothed in Christ's righteousness, having had our iniquities cast into the sea to be remembered no more (Micah 7:19), when we drag our sorry selves before the Father, he isn't standing there, arms crossed, eyebrow cocked, tsk-tsking at us. He's not sighing or sulking. He is more eager to forgive than we are to sin or repent of sin!

Let us then with confidence draw near to the throne of grace, that we may receive mercy and find grace to help in time of need.
– Hebrews 4:16
