Jesus was the very embodiment of love. He was filled with God’s Spirit, who produces the fruit of joy (Galatians 5:22). I imagine that he and his disciples roared in some good times of belly-aching, room-rocking laughter in their collective joy.
The text I draw this from is John 15:12–15, in which Jesus emphasizes how he isfriends with those who truly follow him. He will share his joy, which he possessed first, with them (John 17:13). Of course, it’s true to say that this joy relates to the peace we have with God through Christ.
