Yes.

God’s people should praise him joyfully. Everyone should. That’s what righteous people do. There is no law against joy. Everyone should rejoice when they see bad things happen to bad people. That’s what righteous people do.

People should rejoice at home and in public. People should do good deeds gladly, and bring their parents and leaders joy. Don’t act like you’re mourning during religious ceremonies; you should be enjoying yourself. Even if your life is hard, you should be happy about it. Enjoying your life is the best thing you can possibly do!

God satisfies people’s desires and makes them happy. He commands people to celebrate and rejoice and to make other people happy, and he rewards them with happy lives when they do what he wants. He wants us to be glad to know that he will reward us. He rewards people for being delighted with him and for gladly doing what’s right. He even punishes people for not being joyful. God wouldn’t do those things if it wasn’t good for people to be happy, would he?

Solomon wisely wished for his son to have a happy marriage, and encouraged others to be happy too, because he knew that being cheerful is good for you. David, who always behaved just the way God wanted him to, rejoiced and celebrated a lot, and he said other people should rejoice, too. God himself is often delighted with people, particularly when they do what he wants, and he rewards them gladly. Everything God does is right, so we should follow his example.

No.

God does not approve of people rejoicing over their enemies’ misfortune. And according to Job, that’s not the only kind of rejoicing that’s wrong; it’s also a sin to rejoice over your own fortune. Job was the most righteous person on earth, so he ought to know what he’s talking about.

You should not gratify your desires by doing what you want, because your body’s desires are perverse, and will lead to your destruction. Shun life’s pleasures, so they won’t get in the way of your spiritual growth. You must not indulge in pleasures, or you might as well be dead. God will not answer your prayers if what you’re ultimately trying to get is pleasure.

Those who love pleasure will be punished. Pleasure is not good,¹ and you should have nothing to do with people who are so foolish, disobedient, flawed, and depraved as to love pleasure.

Solomon wisely advised people to refrain from laughing, because he knew that being sad is good for you. Pleasure won’t do you any good; it only brings poverty. Only a fool would go and have fun at a feast; it’s better to join the mourners instead, because you are going to die, and you should keep that in mind.

When the Babylonians rejoiced and were glad, God thought it was a shameful disgrace. God will never forgive people who insist on joyfully laughing and partying when he clearly wants them to be crying. It doesn’t matter if you’re celebrating because it’s a holy day; God will make you stop.

Jesus wants you to suffer when you don’t deserve it, just like he did. Anyone who doesn’t hate their life isn’t a real Christian. So don’t laugh, or God will make you cry. Grieve over what God is doing to those around you, or you too will be punished. Don’t even think about enjoying your life, or you will die and go to hell!
