2 Corinthians 5:21
God made him who knew no sin to be sin for us, so that in him we might become the righteousness of God.
Beloved, Christ’s sacrifice has given you righteous standing before God. This is true! But look above and you will see that the verse does not stop at saying you become righteous. (which is more than sufficient) It says you have become NOW the righteousness of God in Christ. This is huge! The writer does not leave you in a position to even think you can be non righteous before God. Why? Because it says this righteousness is of God. You cannot convince yourself that your righteous standing can be lost because to do that, you will need to arm-twist the verse above to think that way. God’s righteousness is eternally righteous. Period.
