Why is it not a grand enough purpose to be in God's family, be loved and chosen by him, promised eternity of relation with him, have thousands and even millions of brothers and sisters and friends in Christ, be co-workers with him in his work to bring others to himself, and share in his glory?

Why do we also need to "become God" for it to be grand enough?

The Bible never says anything close to plainly that we will "become God." Given that, as I said, we ought to hold back such a whopper of an assertion.

It seems that such overreaching was the sin of both Satan and the first people. Both were tempted to be "like God" in ways God forbade. Seems to me this "become God" thing is the same type of temptation. "I will be like the Almighty," said Satan. "You will be like God," he told Adam and Eve. It springs from ingratitude, the thought that there is something that God is keeping or hiding from us, some secret prize that he's withholding.

God has been gracious enough to reveal some of the mysteries he planned for us. Let's be careful of speculating about ones he hasn't made clear, especially when they are in the being "like God" category. Tap dancing with blasphemy is not the choice of sober minds.

Also, whatever "partakers of the divine nature" means, it certainly does not have to mean we "become God." As a matter of fact, extrapolating such an idea from that verse seems reckless interpretation.
