"Must confess each sin that we commit as we commit them (keep a specific inventory) as an additional requirement to remain cleansed/saved and if we forget a sin we are toast!" -- is a pretty tall order!I am very curious to hear from those that think you DO have to ask forgiveness every time you sin what happens if you don't.
Are you no longer a child of God? What is He going to do to you if you die with uncompressed sin?
Notice that - If we confess our sins, he is faithful and righteous to forgive us our sins, and to cleanse us from all unrighteousness (vs. 9) is IN CONTRAST TO - If we say that we have no sin, we deceive ourselves, and the truth is not in us (vs. 8) and - If we say that we have not sinned, we make him a liar, and His word is not in us (vs. 10).
