Ever consider that Jesus was largely a happy person. One who lived in the moment; absolutley trusted in the goodness of Hid Father in each and every situation.
This sunday we looked at fear, stress and worry can strip us of our happiness.
When we consider the idea of happiness we are encouraged to seek first the kingdom rather then seek after happiness. Seek happiness and you'll miss God and happiness. Seek Christ and His Kingdom and you'll get both Christ and happiness.
If you want to hear this from a different angle, please consider this hebrew idea on Delight and Desires. Pretty cool.
