So many Christians are being utterly destroyed by Satan and the kingdom of darkness. Satan knows that if you do not repent then you will become his slave and a servant to Sin. And Paul also warns us very clearly in 2 Corinthians 4:15-22
What then? shall we sin, because we are not under the law, but under grace? God forbid. 16Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness? 17But God be thanked, that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine which was delivered you. 18Being then made free from sin, ye became the servants of righteousness. 19I speak after the manner of men because of the infirmity of your flesh: for as ye have yielded your members servants to uncleanness and to iniquity unto iniquity; even so now yield your members servants to righteousness unto holiness.
For when ye were the servants of sin, ye were free from righteousness. 21What fruit had ye then in those things whereof ye are now ashamed? for the end of those things is death. 22But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life.
