My analogy is sort of a way of saying what this says:
First John 3:9 does not teach the Reformed doctrine of the perseverance of the saints. Indeed, no passage does. God perseveres.
Saints at best fail daily. First John 3:9 is a call to holiness. Our new natures are pure and holy. Let us live in our experience like we are in our position. Of course, there is a mystery here. John said in 1 John 1:8,10 that
believers cannot attain to sinless perfection in their experience. However, we can allow our new natures to dominate our experience so that we live consistently godly lives. May we live like who we are: children of the Holy One who has saved us by His amazing, free grace.
From here:
Grace in Focus: "Do Born Again People Sin? 1 John 3:9" by Bob Wilkin
Or from here:
1 John 3:9 - No one who is born... - Verse-by-Verse Commentary
Whosoever is born of God doth not commit sin -
This passage must either mean that they who are born of God, that is, who are true Christians, do not sin habitually and characteristically, or that everyone who is a true Christian is absolutely perfect, and never commits any sin. If it can be used as referring to the doctrine of absolute perfection at all, it proves, not that Christians may be perfect, or that a “portion” of them are, but that all are. But who can maintain this? Who can believe that John meant to affirm this? Nothing can be clearer than that the passage has not this meaning, and that John did not teach a doctrine so contrary to the current strain of the Scriptures, and to fact; and if he did not teach this, then in this whole passage he refers to those who are habitually and characteristically righteous.
