Humor is also one of His creations.
Sure, when it’s godly. But to rationalize something ungodly as just humor doesn’t justify before Him. There are a lot of warnings about watching our words in Scripture, including from Jesus in Matthew 12:36-37, and that’s all the more so because many times where we have the most freedom is in what we say:
“O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh. A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things. But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment. For by thy words thou shalt be justified, and by thy words thou shalt be condemned.”
