A key thing is what we mean by repent.
Before conversion, everyone is dead in sin. No one is perfect. So if repent is meant as a work of behaviour of lessening sin BEFORE conversion, then that doesn't save anyone.
Repent is a 'change of mind, heart' from unbelief in Jesus to belief in Jesus.
That's all. It can't be good behaviour. A believer can only commit to good behavior for Jesus, having already been converted by Jesus.
