I have blotted out your transgressions like a cloud
and your sins like mist;
return to me, for I have redeemed you.

Sing, O heavens, for the LORD has done it;
shout, O depths of the earth;
break forth into singing, O mountains,
O forest, and every tree in it!
For the LORD has redeemed Jacob,
and will be glorified in Israel.
Isaiah 44:22-23

I love the extention of this promise to Israel to the ends of the earth, in chapter 45. Jesus blotted out our sin once and for all!

"Turn to me and be saved,
all the ends of the earth!
For I am God, and there is no other.
By myself I have sworn;
from my mouth has gone out in righteousness
a word that shall not return:
'To me every knee shall bow,
every tongue shall swear allegiance.'
Isaiah 45:22-23
