The best work on this is undoubtedly Jonathan Edwards's Religious Affections. In that book, he makes a painstaking case that emotions are not a reliable indicator in any way whatsoever of true religious experience. Interestingly, Edwards's work came before the late 1800's, when the emotional revivalism of people such as Charles Finney became so much more influential than the perceived coldness of Calvinism.
I agree with Ryan Frame that the Bible has plenty of emotion in it. In addition, I would argue that the Bible does not regard those emotions as good indicators of your standing with God. They are simply a normal part of being human.
Perhaps other churches are different, but my church does not regard the Fruits of the Spirit as emotions. They are virtues. That is, they are character traits of a person that affect how he behaves. The Holy Spirit works in a person's heart to produce that fruit. See Phil. 2:12-13.
