Jesus says:
Therefore I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.    –    Matthew 5, 20
Be ye therefore perfect, as your heavenly Father.    –     Matthew 7, 48
Strange as it sounds, but some people actually try to be as perfect as the Heavenly Father. They exert themselves enormously, so as not to go wrong. Really exhausting!
Pay attention so much to their own behavior, whether it is right and so, that they often have more no eyes for others. – Is this so willed by God? So well treated and thinking only about themselves?
How can man be so arrogant and so want to be like God! We cannot be so perfect!
It’s good when you have ideals to emulate Jesus. But if we want to earn something so badly and constantly have to make an effort, the view of Jesus is lost. We only see ourselves.
Then it is not too far off, and we only see our failure. The more we exert ourselves, the worse it is for us!
That is why Jesus has opened for us another way: the gospel of salvation. How great!!! Every sin forgiven, He simply wipes it out! What can better happen to me,  this forgiveness of my guilt and of my failure!
We soon realize: Everyone sits in the same boat. Whether someone is almost sacred, or a really great sinner: We need forgiveness and redemption, because we are just sinners and failures. We are never as perfect as God!
When Jesus forgave sin and we finally understand and access this, then we are indeed “sinless”. We then pure and holy. Or is there still a residue of sin in us where Jesus has not cleansed us? No! We are really spotlessly clean and white. Then verses above are reality: our justice, Jesus, is bigger and better than that of the scribes and Pharisees. We are perfect as the Heavenly Father.
And if we still sin again, – that comes before yes, we are still people – so Jesus forgives and redeems us newly. Depending on when we come and ask Him. (Some need a long time, others are much faster, because they want to be pure again quickly).
Thank you, Jesus, you wipe away my faults and my failures! Nothing remains of it all in your memory and I may even forget it! You live in me and make me constantly holy and pure. Oh, how good that this battle is over! Now I can pay attention to other people and proclaim you by word and deed. Now I can live with your mercy and do not need to constantly think of me! You are my Savior, thank you !!
