Mat 5:20 "For I say to you that unless your righteousness surpasses that of the scribes and Pharisees, you will not enter the kingdom of heaven."
2 Cor 5:21 "He [God] made Him [Jesus] who knew no sin to be sin on our behalf, so that we might become the righteousness of God in Him [Jesus]."
Rom 7:15-8:1 tell us we will struggle with sin while we live in our mortal bodies, but in Christ, our sin is erased; we are made holy in Him. There is no other way. In Christ, we do not face condemnation, but are passed from death to life ~ now in spirit through the moment we take our last breath; then, for eternity...where there will be no more sin.
