Life on earth is a trust. This is [one of the] metaphors for life we find in the Bible. Our time, energy, intelligence, opportunities, relationships, and resources are all gifts that God has entrusted to our care and management. We are stewards, or managers, of whatever God gives us. This concept of stewardship begins with the recognition that God is the owner of everything and everyone on earth.
We never really own anything during our brief stay on earth. God just loans it to us while we’re here. It was God’s property before you arrived, and God will loan it to someone else after you die. You just get to enjoy it for a while.
-- Rick Warren in “What on Earth Am I Here For?”
