It is a mistake to assess spirituality simply on the basis of a person's emotional display. What you want to be careful of is looking around at people in the church service and seeing people really into it – on their knees, people singing with glazed-over eyes, people expressing a lot of emotion, people weeping – and drawing the conclusion that because people are responding emotionally that they have a deeper connection with God or a more mature faith than the person who is not reacting emotionally at all. This is a profound error… Emotional response is not in any sense a Scriptural measure of spiritual maturity.
