“Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.”
King James Version (KJV)
3:4 Whosoever committeth sin - Thereby transgresseth the holy, just, and good law of God, and so sets his authority at nought; for this is implied in the very nature of sin.
1Jo 3:4 Whosoever committeth sin transgresseth also the law. The very act of sinning is a breaking of law. Sin is the transgression of the law. "Sin is lawlessness" (Revised Version).
