And since Christ's righteousness has been imputed to us who put our faith in Him, then we're good to go because God sees us as having done the righteous deeds necessary to enter heaven.
Galatians 3:27 For as many of you as were baptized into Christ have put on Christ.
Philippians 3:8-9 8 Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ 9 and be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith—
Galatians 3:23-27 23 Now before faith came, we were held captive under the law, imprisoned until the coming faith would be revealed. 24 So then, the law was our guardian until Christ came, in order that we might be justified by faith. 25 But now that faith has come, we are no longer under a guardian, 26 for in Christ Jesus you are all sons of God, through faith. 27 For as many of you as were baptized into Christ have put on Christ.
2 Corinthians 5:21 For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.
Seriously that is your best arguement?
