God is the source and owner of all things in creation. Ps24:1 Psalms 50:10
He owns it because He created all things. Gen1:1
Everyone who 'owns' anything is merely a custodian, a trustee and steward of it. Matt25:15
Every steward, custodian will give an account on what was entrusted to their care. Matt25:19
God entrusts things based on
1. How faithful we are with the things already entrusted. Matt25:21
2. Covenant relationship he has with people. Deut8:18
3. Our position in His will and purposes. 2 Corinthians 9:8
4. Our position in organised structures and systems. john4:38
