1st john 1:9 means that God is not expecting perfection but relationship.

You went to Sunday school. But, you never accepted Christ as your sacrifice for those moments of shortcoming in your human perfection. But, you saw someone and instead of accepting your shortcoming and Christ as your sacrifice, you rejected your shortcoming in perfection and Christ as the efficient sacrifice. It used to be a lamb a day; just for the priest and a few more for the congregation. But, Jesus took the few in hand and multiplied in efficiency. He is the sacrifice. Instead, you must have decided to say "...this is me and there is nothing wrong with it. I am perfect." But, this will not explain your desire to see someone as a "passing away" and you don't know why you are bothered with them because they don't think about you or anyone else with such continued interest. Instead, they read Hebrews 9, 1st John 1:9 and John 3:16. If it is really ok, then you don't need anyone as a "passing away" while you remind yourself that "..there is nothing wrong." You are perfect. There are some people who flipped a coin and took Christ as that sacrifice and didn't worry about anyone else. They took the chance with the flip of a coin and it worked. There was an umbilical sense of knowing that you are ok and that the 10 commandments are an innate part of you. In light of that shortcoming in perfection, you know you are ok as you read 1st John 1:9 in the faith of Abraham. 1st john 1:9 means that God is not expecting perfection but relationship. Your self esteem is not the claim of perfection but the reality of an arbiter and Father who is just like the father figure or mother figure in your house or the school teacher who scolded you, taught you in love and then forgave you, teaching you grammar, serving you that home cooked dinner or buying that Action figure or doll on sale before it was your birthday. Your cousin's mother did it differently but that is the general idea in every parent-child relationship where no body is perfect. It works. With Jesus, it is finished. Is it possible that someone could worship rejection and the power one feels in rejecting/shedding others? You have family once in this brief experience of life who love you too very much and its really nice to have family around every so often. Whether you are first born or the last, everyone is a child of God. See Psalms 82. David was in the middling group. He was not first born.
