Knowing God leads to self-control. Self control leads to patient endurance, and patient endurance leads to godliness. 2 Peter 1.6

It seems that everyday, stong negative emotions can grip us. God's will is that we don't live out of those negatvie emotions. Distrust them, test them, and give them over to God.  Emotions change, God does not.
In Hebrews 10.38, God teaches us that we should live by faith. We must place faith above our feelings. Gods intent is that we don't live on emotional roller coasters, as a matter of fact, Jesus left us with His Peace, that incredible gift to all believers!
C.S. Lewis gave us some great advice: "Don't bother much with your feelings. When they are humble, loving, brave, give thanks for them; when they are conceited, selfish, cowardly, ask to have them altered. In neither case are they you, but only a thing that happens to you. What matters most is your intentions and your behavior."
Emotions...who's in charge of yours?
