Simple enough.
Simultaneously saint and sinner. We need to confess because we still sin every day in thought, word, and deed, and we hear forgiveness every day because we’re beloved children of God.
Really? You think that no one can go a single day without sin? Where is that in the Bible? Jesus told the woman to 'go and sin no more', so why would He have said this if it was impossible to do?
No, the problem is with man's twisting what Jesus said. The Word of God specifically tells us what sin is and Jesus, the living Word of God, tells us that through the power of His spirit in us, we too can overcome as He overcame the temptations of the devil. So, NO!, we do not necessarily need to repent everyday, however, we should take time everyday in prayer to thank God for the blessings we receive and the tribulations we bear in His Name.
"To he who overcomes!" Maybe it's time the churches start preaching and teaching what it means to be an overcomer, because Jesus certainly did and He left us an example that wee should follow, that we should not be lead astray by every wind of man made religious doctrine wherein there is no profit.
