For as by the one man's disobedience the many
were made sinners, so by the one man's obedience
the many will be made righteous.
Romans 5:19
For our sake he made him to be sin who knew no sin,
so that in him we might become the righteousness of God.
2 Corinthians 5:21
Because Christ became our substitute and bore the wrath
of God in our place, he has provided the atoning
sacrifice for our sins, and the sins of all who believe.
Just as God imputed our sins on Christ, "he made him to be sin",
so God imputes the righteousness of Christ - a righteousness
that is not our own - to all who believe in Christ.
Because Christ bore the sins of those who believe,
God regards and treats believers as having the legal status of
"righteousness". It belongs to us because we are
"in him", that is, "in Christ".
The righteous one, my servant, [shall] make
many to be accounted righteous.
Isaiah 53:11
