'In Sin' in the Bible

No one who maintains union with him lives in sin; no one who lives in sin has ever really seen him or learned to know him.

No one who has received the new Life from God lives sinfully, because the very nature of God dwells within him; and he cannot live in sin, because he has received the new Life from God.

We know that no one who has received the new Life from God lives in sin. No, he who has received the new Life from God keeps the thought of God in his heart, and then the Evil One does not touch him.
