1 John 5

Shall we continue in sin that grace should (have to keep) abound(ing)? God forbid! How shall we who are DEAD to sin live any longer therein? [Rom. 6:1,2] We know that anyone born of God does not [deliberately, knowingly, habitually] practice committing sin. [1 Jn. 5:18]

How do you know it’s sin? The Holy Spirit keeps telling you. When in doubt, cast it out! If God’s gift of faith does not sanction it, get rid of it. Decide with your will that it can’t stay, then ask God to give your the strength to resist it. Keep asking! God wants you to walk in perfect freedom from sin (and its consequences).
