We are taught in the Epistles of the Bible that we are to always be of a sober mind. Being happy or content does not translate to laughing like a loon at the drop of an unkind word.......humor usually is at the expense of someone else.....even when or if not, it has no place in the conversation of faith.......perhaps when outside the conversation, but that phrase in itself is accusative is it not?
first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye. (Matthew 7:5)
When you read passages like this, how can you not believe Jesus has a sense of humor? Wouldn't you expect someone who makes a humorous exaggeration like this to have a sense of humor?
