How do we know that the earth and its fullness belong to God?

The ownership of the earth and its fullness by God is explicitly articulated in Scripture, particularly in Psalm 50:10-12, which states, 'For every beast of the forest is mine, and the cattle upon a thousand hills.' This shows that not only does God claim the earth, but every living creature and natural resource is also under His dominion. By acknowledging that all things are created and sustained by Him, we understand our position as caretakers of His creation, rather than masters of it. This realization should inspire both humility and stewardship in our actions.
