Ro 6: What shall we say, then? Shall we go on sinning so that grace may increase? 2 By no means! We died to sin; how can we live in it any longer? 3 Or don't you know that all of us who were baptized into Christ Jesus were baptized into his death? 4 We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.
So, we both have sin in our lives.
The only real questions should be, (1) Are we happy with that or are we not?, and (2) Are we proud those sins hung Christ on the cross, or do we lament that evil we had done?, and (3) What does it mean if we take his grace for granted?, and, finally, (4) Does not caring about our sin mean we might have missed the boat?
Look at your questions. They're all about YOU. You're looking at YOU. The devil wants you to look at YOU. YOU will never be perfect.
What is the basis of our hope and salvation? Does it have anything to do with ourselves? No. "Having begun in the Spirit are we now made perfect by the flesh?" Galatians 3:3. Our hope and salvation has everything and only to do with Jesus and what he did. God isn't looking at YOU. He's looking at his perfect sacrifice, the Lamb of God, Jesus Christ. Because His sacrifice was perfect, you are perfect. "As he is, so are we in this world." 1 John 4:17. Stop looking at YOU. "Look to Jesus, the author and finisher of our faith." Heb 12:2.
The shadow of Jesus was the animal sacrifice in the old testament. The priest, the judge of the sacrifice, never inspected the one bringing the sacrifice. But the priest very carefully inspected the animal that was to be sacrificed to see if it was perfect. God doesn't look at you. He looks at the perfect Lamb of God, His Son, and is perfectly satisfied. You and I are therefore free.
It's like you're coming to the priest and wanting him to notice how sorry you are for your sins and all the things you're doing to show your sincerity. But God never ordained the priest to inspect the one for whom the sacrifice was being made, only the sacrifice itself. In the same way, God doesn't inspect you as you, he inspects Jesus as you. We are accepted by grace though faith in his Son, nothing else. Adding your little bit is bringing in "another gospel" which scripture curses TWICE (Galatians 1:8-9) and calls "falling from grace" (Galatians 5:4). So to allow the blood of Jesus its effective work and grace to flow in your life, we must relinquish self-righteousness and self effort.
