"Don't trust your feelings!"

Christians are often told: "Don't trust your feelings."
That is not always helpful because our spirit and the Holy Spirit speak to us through our feelings. So don't tune out to your feelings. Listen.
Christians are aften told that anger is wrong. I wish we taught that anger has a place but hatred hurts both us and the other person. It acts like a curse.
Could I suggest that we reserve our misgivings for hate, bitterness, hostility, resentment and any feeling leading to revenge against another. Keep 'anger' free of negative judgement unless it is used sinfully.
It is said: "Do not let the sun go down on your wrath." Please interpret this to mean that anger needs to be expressed. Look at anger as energy from God to get us talking, confronting, standing up to injustice, unfairness, hurt and oppression.
Be guided by: "Be angry but sin not." Ephesians 4:26. Take this to mean that you can confront the issue without putting down the person. Sin enters in when we call names, put down or intentionally hurt another. Speak the truth in love.
