In Christ Jesus We Have Wisdom, Righteousness, Salvation, And Holiness

1Co 1:30 It is because of God that you are in union with the Messiah Jesus, who for us has become wisdom from God, as well as our righteousness, sanctification, and redemption.
ISV

To those of God’s selection, Jews and Greeks, Christ is the power and the wisdom of God.
Because what seems foolish in God is wiser than men; and what seems feeble in God is stronger than men.
For you see God’s design for you, my brothers, that he has not taken a great number of the wise after the flesh, not the strong, not the noble:
But God made selection of the foolish things of this world so that he might put the wise to shame; and the feeble things that he might put to shame the strong;
And the low things of the world, and the things without honour, did God make selection of, yes, even the things which are not, so that he might make as nothing the things which are:
So that no flesh might have glory before God.
But God has given you a place in Christ Jesus, through whom God has given us wisdom and righteousness and salvation, and made us holy:
So that, as it is said in the holy Writings, Whoever has a desire for glory, let his glory be in the Lord.
