My lips and my soul, which you have redeemed, are glad and sing to you.
(Psalm 71:23) All Bible texts Luther Bible 1912. (DeepL)

Verse 19:

God, your righteousness is high, who do great things. God who is like unto thee?

Verse 21:

You make me very great and comfort me again.

The psalmist has great self-confidence. I also have that as a reincarnated Jesus of Nazareth.
