The dependence of mankind is constant and absolute. They cannot exist a moment without the immediate exertion of Divine power. When God brought them into being, he gave them no power to preserve themselves in existence. They are no less dependent on God for preservation than they were for creation. This is true of all created beings. They have no self-supporting, or self-preserving power. In God they live, and move, and have their being. There is precisely the same connection between God and all his creatures, as there is between cause and effect; and it is well known, that an effect can exist no longer than the cause which produced it continues to operate.

The point
Creatures depend on God's continual power for existence just as an effect depends on its cause.
