I can't speak for every church but, what comes to mind here for me, and i hope it answers this question is.
Romans 8:5-8 5 Those who live according to the flesh have their minds set on what the flesh desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires. 6 The mind governed by the flesh is death, but the mind governed by the Spirit is life and peace. 7 The mind governed by the flesh is hostile to God; it does not submit to God’s law, nor can it do so. 8 Those who are in the realm of the flesh cannot please God.
When it talks about the mind here it is the word phroneó when used in the context of romans 8:5 and 6 i found this definition, to direct one's mind to a thing, to seek or strive for; to seek one's interests or advantage; to be of one's party, side with him, Which is why i like the niv translation of being governed by the flesh or governed by the spirit. Now in ancient times emotions were thought to come from the heart, we now know they come from the brain (or maybe the stomach we have gut feelings). If we consider that the brain is a part of our flesh than we can begin to see that emotions are also a product of our flesh. Now although physical feelings like fire being hot, or whether we are sick or not are very beneficial, emotion is a little different. Acting from anger, sadness, fear or even happiness can have huge negative impacts on our lives and are an example of being governed by the flesh.
Galatians 5:22-23 But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, 23 gentleness and self-control. Against such things there is no law.
Although most people think of things like Joy and peace as emotions they are something totally different, and are given to us by the spirit. Those who are governed by the spirit live there lives from those fruits and not from the circumstantial emotions of the flesh. I hope that is clear enough to understand.
