If you're covering it, you haven't repented of it. If you haven't repented of it, you've opened that "door" whereby the Enemy and his evil minions have LEGAL RIGHT to enter with the express purpose of your destruction and you need deliverance! We must strive to always confess our sins every day -- even several times throughout the day. Repentance is "turning away from" so if you confess with your mouth only and continue in the sin, you're committing willful sin (iniquity) thus opening the door. UNDERSTAND what sin does . . . don't listen to the Enemy . . . don't buy into his lies. Put on your armor every day, pray, cover yourself with the Blood of Jesus and RESIST the devil and he WILL flee you! AMEN.
If you've been involved in willful sin brethren you must assuredly need deliverance! If you haven't there is still a good change you need deliverance . . . as familiar curses on both your mother's side and your father's side may have give the Enemy legal right. In addition, there are curses spoken over you by others . . . even word curses you have spoken over yourself that you aren't aware of. Al of these things cause open doors.
