Jesus is portrayed throughout the Gospels expressing all the fruit of the Spirit (love, joy, peace, gentleness, goodness, faith, meekness, temperance). He does so to perfection. These are what so endear Him to those that follow Him. The fact that the Scriptures nowhere record His laughing with His disciples is something that, quite frankly, disappears from the radar when you consider His purpose for coming. In the end, His followers rejoice that "The Son of God loved me and gave Himself for me," and care very little that He failed to demonstrate a divine sense of humor or laughed at one of Peter's jokes.
