Revelation 12:10 - "Now is come salvation, and strength, and the kingdom of our God, and the power of His Christ: for the accuser of our brethren is cast down, which accused them before our God day and night." You will be a miserable Christian if you don’t learn the difference between Holy Spirit conviction and Satanic accusation. When the Holy Spirit convicts you of a sin, He will not just make you feel bad all over. He will put His finger right on the sore spot and push. He will convict you specifically and He will convict you legitimately. Now if the devil doesn't convict you of all your sins in general, he will try to accuse you of a specific sin for which you have already been forgiven. And he will fight a losing battle because if you put your sin under the blood of Jesus Christ and it comes up again, it’s not God bringing it up. Are you under conviction or accusation today about an un-confessed sin?
Read Revelation 12:9-11. Claim the powerful blood of Jesus to cover your sin. Repent and believe!
