There is a difference between spiritual and emotional.
Spiritual fruit - The fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, meekness, temperance: against such there is no law. - Galatians 5:22-23
Emotional, on the other hand, is something totally different and tends to the flesh. There is a change of heart that is neither flesh nor mental reasoning. I believe the change of heart, or sanctification, is superior to mental doctrine, or any kind of noise one may make.
