In Psalm 2:5 we read, "He who sits in the heavens laughs; the Lord holds them in derision." This is the only place that I know of that talks about God laughing. The context shows that the human beings plot to thwart the plan of God in Christ, vs.1-4. The reaction of God is that he laughs. Could you imagine an hundred ants plotting to take a grown adult down, that is funny. You can wipe all those ants out easily and quickly. Why does puny man think that he can stifle anything that God does or promises he will do? Humans can be fool-hearted sometimes when it comes to God. We are really nothing in comparison to God. Notice that our text says, " the Lord holds them in derision." He will make them a laughingstock for their foolish notions about his plan in Christ. After his laughs at their crazy plot, he will get the last laugh in deriding them, scorning them, to cause them to stammer at his great power and wisdom. Paul said we cannot mock or make fun of God and his laws. "Do not be deceived: God is not mocked, for whatever one sows, that will he also reap. For the one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life." What we sow is what we reap, that is an immutable law in our universe. When we say that someone breaks the law, in reality we only break ourselves against the law, it stands true and firm. May we ever respect God and his laws, he is sure and constant in the world we live in. I am glad that God has a sense of humor. I think humor helps provide balance in our lives. There are so many sad and sorrowful things in this world, so a little humor and levity give us a balance in our hearts. I am reminded of the proverb, "A merry heart doeth good like a medicine: but a broken spirit drieth the bones." Prov.17:22. The adage we use today is that laughter is the best medicine.
