"Then Jesus came to them and said,"All authority in Heaven and on earth belongs to me," (Matthew 28:18 NIV (c)1984).
God also owns everything in world and all who live in it.
"The earth is the Lord's and everything in it; the world and all who live in it," (Psalm 24:1 NIV (c)1984).
God then delegates authority, responsibility, and wealth to people and institutions. What? Well, let me explain. God is the owner of everything and we are His stewards. We take care of His property for Him. The best biblical illustration of this is the parable that Jesus told in Matthew 24:45-51 where the master of the household puts a servant in charge of his household, possessions, and other servants while he goes away on a trip. When the master comes home, he will reward or penalize the servant based on the servant's care of others and behavior.
God places us in charge of his people and possessions. We are his stewards, accountable to him for the job we do in caring for what is entrusted to us.
