John 15:14, Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me.
The World we live in is full of energy sources, this has at least been very well proven by science, for a light bulb to continue lighting it needs to be connected to a source of energy. For a tree to continue growing and not die it needs to be be connected to the soil.
In the same vain for man to survive this world we need to be connected our source of energy and that is none other than our maker. When the Lord created us he breath into us by that process we became living creatures. Our very essences stems from the Lord.
Our Spirits must be in tune with the heavenly and our souls must be purged. This way we will be able to abide in him and him in us. For it is by having connections with our source always that we will continue to function and survive in this passing life.
