Nothing belongs to us, whatever we have is His. Everything is a gift from Him, He can take it back anytime. The only way we can pay back to Him for all these gifts is to live according to His Will.
From a lecture by Prof. Darshan Singh on Sukhmani Sahib (a section of Sri Guru Granth Sahib).

There was a school of fish who wanted to find out what water was.
So they went to a wise fish.
"You're in it!" he said.
"It is above you and beneath you.
To the left and to the right.
It is within you and without.
You live, and move and have your being in it."
They thanked him, and swam away.
Then they all got together and decided that they still didn't know what water was!
Yogacharya often told this Fish Story explaining how the nature of water is like nature of God.
