For anyone who thinks that Christians struggle with Sin:

1 John 3:9 says that the seed of God remaining in us makes it so we CANNOT sin because we have been born (again) of God.

Paul seems to indicate this same thing in Romans 8:1-16 when referring to the Holy Spirit.

Ezekiel 36:25-27 also makes it clear that it is the Holy Spirit who, CAUSES us to keep His commandments and judgments and do them.

I note that Simon the Sorcerer did not receive the Holy Spirit upon his baptism because he was not repentant when he believed and was baptized into the Christian community.
