Does the Bible Say That Someday Everyone Will Worship God?

Questions about whether the Bible says that someday everyone in the world will worship God, the purpose of worshiping God, and whether it might be the case that God has created another universe where that creation also gives him glory.

• Does it say anywhere in the Bible that someday everyone (all the world) will worship God? [Note: after recording this episode, we also came across Psalm 66:3–4, which says that “all the earth will worship” God, but also that his enemies will give him “feigned obedience.”]
• What is the purpose of worshiping God?
• If God maximizes his glory in this universe, is it reasonable to think he’s maximized his glory in another universe or in some other creative act that involves his creation giving him glory?
