If we are in Christ, then we have His righteousness and it is not given to us in degrees. No one receives more or less of it. It is the perfect righteousness of Jesus Christ, and by faith we receive it in its fullness!
We are to measure ourselves by His righteousness alone and not by anyone else’s righteousness. Read this passage.
We do not dare to classify or compare ourselves with some who commend themselves. When they measure themselves by themselves and compare themselves with themselves, they are not wise. We, however, will not boast beyond proper limits, but will confine our boasting to the field God has assigned to us, a field that reaches even to you (2 Corinthians 10:12-13).
Paul is saying that there is a rule you can use to measure yourself. Everyone who truly repents, believes in the perfect righteousness of Christ, comes to Him in faith, and believes in His work on the cross, is made perfectly righteous in the sight of God. You may not have everything worked out yet. Through the power of the Holy Spirit, there is still a daily work of sanctification in your soul realm (see Rom. 12:2). The Beloved accepts us, and the very righteousness of Christ has been imputed to us!
