Emotions are our feelings ... happiness or sadness. These don't come from our spirit man ... they come from our soulish realm. There's nothing wrong with feelings as long as they stay in line with what our spirit man wants to do.
Joy is not happiness ...it's not a feeling. It comes out from our spirit man, and is one of the fruit of the Spirit. We can have joy and not be in happiness.
A lot of times we start out in the flesh ... our soulish realm ... to make something spiritual happen. it isn't too long then that we find ourselves being obedient to what the Spirit wanted to do all along.
Our emotions influence our mind, taking over our thinking. They can change in a split second, depending upon the outward influences.
We have many emotions.
Fear is one of the most dangerous emotions to us as Christians. It can catapult us away from our faith and from God's presence FAST. We are unable to "think straight" when fear takes over.
This is why God tells us in His Word to "fear not". He has not given us the spirit of fear, but of power, love, and a sound mind. A sound mind thinks straight!
