As the ark entered Jerusalem, David worshiped and danced to the point of becoming undignified (2 Sam. 6:16). Michal, David's wife, despised David, and told him so: "How the king of Israel has distinguished himself today, going around half-naked in full view of the slave girls of his servants as any vulgar fellow would!" (2 Sam. 6:20). David replied, "I will celebrate before the LORD. I will become even more undignified than this, and I will be humiliated in my own eyes" (2 Sam. 6:21, 22). Michal remained childless the rest of her life (2 Sam. 6:23).
I've often thought that Michal was childless because the Lord cursed her womb. But perhaps, since Michal wouldn't join David in worshiping to the point of humiliation, David withheld himself from union with her.
Will we join to Jesus, the Son of David, when He is undignified and being with Him means we are humiliated in our own eyes? Jesus became most undignified and humiliated at the cross. Will we dance with Him when circumstances lead to a "cross" in our lives? Or will we despise Him and choose the barrenness that preserves our dignity but means we can bring forth no spiritual life or fruit?
