That makes sense! However, Jesus was teaching in the case of the Sermon on the Mount and elsewhere that no one fully does all of His teachings except Him--making Him the cross candidate.
Jesus taught one must be perfect, not good, to get to Heaven, Jesus died for our sin IMHO, not in spite of our sin, etc.
You appear to making things up. Yeshua didn't say no one could be "perfect"/"complete". He said if you want to be "perfect" sell all our goods, and give the money to the poor, and follow me (Matthew 19:21). As for entering into "the kingdom of heaven" which is "at hand", one must simply be more righteous than the Pharisees (Matthew 5:20). And the "kingdom of heaven at hand" is at hand (Matthew 6:32-34).
Matthew 5:20 "For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, you shall never enter into the kingdom of heaven.
