Again., far from running off on emotions of condemnation and or self righteousness., we hold to the truth that God's love is based on Jesus Christ and His righteous standing. So because of Jesus., we can stand regardless of the world., the flesh and the devil.
We don't stand in our own righteousness but we stand in His. This is what the OP is all about. Our standing is wrapped up in our Great High Priest Jesus. He is our righteousness and only because of Jesus can we hold on steady as we are being the righteousness of God IN Christ. We know that He is our confidence., not in the works we do or don't do.
2 Cor. 5:21 For our sake He made Christ (virtually) to be sin Who knew no sin, so that in and through Him we might become (endued with, viewed as being in, and examples of) the righteousness of God. Amplified Bible
He made Him who knew no sin to be sin on our behalf that we might become the righteousness of God in Him.
NAS.
Those who don't profess this kind of righteousness don't understand what Christ has done for them and can't accept it for others either. So there will always be a major difference in believers who have yet to learn about who they are IN Christ. And we who have learned will continue to profess Christ and His righteousness given to us so they can also learn and be set free from condemnation. Romans 8:1-2
There is therefore now no condemnation for those who are in Christ Jesus. 2. For the law of the Spirit of life in Christ Jesus has set you free from the law of sin and of death.
