Jesus is clear. Once we are His. Once we are forgiven. We should sin no more. If there is a part of our life that we are keeping from God, no matter how big or small we believe it to be we are still rebelling against His standards. Blaspheming the name of God, lieing, stealing, lusting, any form of fornication (sex outside of marriage between a man and his wife), and every other sinful action. We are made a new person in Christ. We need to put the old sinful self behind us. We are, each, allowed to choose our own path and may freely do so. Take care, even though we choose our actions, God chooses the consequences.
