In the first scenario ...the "I" is playing, not the devil's advocate, but the devil. And the second part is sort of like Cain and Abel.

Lucifer was ungrateful ...and wanted to run his own business, and now giving everyone the business who attempts to leave God's business as God's business.

The Bible clearly shows that God makes His business ...our business.  He includes us, yet it is run His way.

If we think we don't like His way, we may need to grow and understand ...but strongly opposing His way, can in no way be accepting His way, or Him.
