I want to show that we should never be surprised by the depths to which sin can take human beings, but by the same token we should never be shocked by the wonders of God’s saving grace. Mannaseh lived a life of perversity, but when he humbled himself God restored him fully.

Isaiah 44:21 English Standard Version (ESV)
The Lord Redeems Israel
21 Remember these things, O Jacob,
and Israel, for you are my servant;
I formed you; you are my servant;
O Israel, you will not be forgotten by me.
