These 15 points are good.
The problem with John Piper’s Calvinistic teaching is that he believes all born-again Christians will walk this way or they weren’t truly born-again. See:
The truth: God has sovereignly chosen to give us free will. Those who are born-again don’t have to obey. God will always enable us to, but we must decide to walk according to the Spirit or according to the flesh. Romans 8:
13 For if you live after the flesh, you must die; but if by the Spirit you put to death the deeds of the body, you will live. 14 For as many as are led by the Spirit of God, these are children of God.
The main thing is to maintain a clean conscience before God and men so we’ll have faith to enter when we see Jesus face to Face, like Paul did:
“..I also practice ALWAYS having a conscience void of offense toward God and men” (Acts 24:16).
