As a “Reformed” Christian I know that there is such a thing as Human responsibility and God’s Sovereignty. I can’t always work it out, but I simply accept that it is true. Rehoboam made his choices and they were poor choices, demonstrating immature and selfish leadership. Yet, as the passage reminds us, God is behind all these things! If God wasn’t behind these things, he would simply be less than he should be. If Rehoboam wasn’t responsible for his actions, then he can’t be held responsible for them!
