Psalm 4:4 Don't sin by letting anger control you. Think about it overnight and remain silent.
This verse doens't say stew on your anger overnight and get more and more angry....it says think about it over night... and Philippians 4:7 says Then you will experience God's peace, which exceeds anything we can understand. His peace will guard your hearts and minds as you live in Christ Jesus... your mind is where your thoughts are... we are to guard our thoughts always.. but expecially when we are angry... listen to what the holy spirit tells us ... if we guard our thougths we don't belive the lies the devil tells us... we ask God how to think about our anger, what to do about what we are angry about... when you sit and listen to the thoughts the devil puts in your head you get angerier and angerier... when you listen to what God tells you to do you began to feel more at peace about your decison about how to handle what you have been upset about... sometimes you wake up and arn't even angry anymore... somtimes you wake up with a resolve and a peace about how to handle the situation that made you angry in the first place.. remember when you are letting anger control you.. the devil is happy... you are believing the lies he puts in your head... when you feel peace about a stiuation you are letting the Holy Spirit guide you and God is pleased! Our choice should always be to please God.
