A quote from S. Wigglesworth

"Take your position from the first epistle of John and declare, “He who is in [me] is greater than he who is in the world” (1 John 4:4).

Then recognize that it is not you who has to deal with the power of the Devil, but the Greater One who is in you.

Oh, what it means to be filled with Him! You can do nothing in yourself, but He who is in you will win the victory".
