He created us for him.

When we die, we either die eternally or are claimed by him eternally. Our bodies, souls and minds were given, but can be taken away.

The universe was made and is sustained by his word, and it will end by his word. 

The gifts of our lives are not something temporal, God continuously gives us existence. Jesus the living word will return to judge those who will keep those gifts and those who will have them taken away. 

If we were true masters of our body we would live forever, never taste heaven, hell or purgatory. God allows us to cooperate with his divine will or reject it, but everything is still by his will.  This is at least what I have gathered after reading Peter Kreeft on Aquinas and listening to Dr. David Anders.
