Great reference, especially considering the unbeliever who has been possessed and then relaxed and then re-entered.
One great thing about Christ, though, is that until a human suffers the first death, separation of soul from body, that human still has an opportunity for salvation, then after salvation, no matter how heinous the sin, one still has an opportunity to confess that sin, turn away from sin, and return to a fellowship with God. Nothing is more powerful than the love of Him.
(Those who continue to rebel after salvation might risk sinning to the point that within His plan, they serve no more useful purpose, or if you will, commit a sin unto death and are brought home to the Lord, leaving many rewards on the table as eternal memorials to the foolishness of those who stray from Him and His plan.
