The anger of Satan who knows his time is short is being expressed through his violent world and has infiltrated the church, paralysing and preventing its true unity and effectiveness.
Demonic attacks of resentment, unforgiveness and anger on the thought life of the disciple cannot be tolerated, this requires honesty and confession not fear and cover up.
Matthew 5:21 ¶Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:
22 But I say unto you, That whosoever is angry with his brother shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.
The Holy Spirit has come to conform His bride/church to His standard of love and obedience.
