“And grieve not the Holy Spirit of God, whereby ye are sealed unto the day of redemption. Let all bitterness, and wrath, and anger, and clamor, and evil speaking, be put away from you, with all malice.” ((Ephesians 4:30-31))

Bitterness creates a climate for the devil. Did you know the devil is bitter? In Revelation 12:17, you find the devil pursuing the nation Israel—the dragon pursuing after the woman. The devil has bitterness, a vendetta against God’s holy people, and he is pursuing. He’s trying somehow, someway, to hurt them.

I’ve seen some Christians with bitterness in their hearts. I don’t know where they got it. Evidently someone hurt them. But the real problem is, there’s a root of bitterness down there in their heart, and they’re like the devil.

Are you bitter? If so, in that regard, you are like the devil. If you’re not careful, before long you’re going to be full of the devil. Don’t let another day go by without bringing that bitterness to God and asking Him to help you release it. – LWF
