Where does it come from?

Where is it? Where does it come from? Where does your strength come from? Know this, I am your strength. I am your shield. I am your great reward. I said in My word that My joy is your strength, yet many of My people have looked to and chosen to rely on another. Many have chosen to rely upon the strength of the flesh. Many choose to rely upon that which seems right to a man, the world and emotions. I tell you, do not trust in and rely upon that which will fail. I said, when you are weak I am strong. I said I will strengthen you. For lo, I have caused you to be more than a conqueror. In Me is fullness of joy. In Me is all you need. Walk by faith, not by sight. Stand firm upon the rock of your salvation. When you have done all to stand, stand therefore. For I am with you even till the end of the age sayeth the Lord.
