How can we glorify God through our emotions?

In this video, Carlton McLeod discusses the range of emotions that are present throughout the Bible and in the lives of biblical characters. You see passion and love and worship. You see anger. You see great joy. You see despondency and sadness. You see hopelessness. You see it all. He argues that there is a middle ground between being overly emotional and being robotic, and that emotions must be under control. 

However, he also emphasizes the importance of being able to feel and express emotions in worship and in response to God's word. McLeod believes that emotions can be a positive thing when they are guided by the Holy Spirit and that they should not be stifled or ignored.

Romans 12:15 (NKJV) - "Rejoice with those who rejoice, and weep with those who weep."
