The Father that dwelleth in me, He doeth the works (ὁ δὲ πατὴρ ὁ ἐν ἐμοὶ μένων, αὐτὸς ποιεῖ τὰ ἔργα)
The best texts read, ὁ δὲ πατὴρ ἐν ἐμοὶ μένων ποιεῖ τὰ ἔργα αὔτου; the Father abiding in me doeth His works. Philip doubts whether Christ is in the Father, and the Father in Him. The answer is twofold, corresponding to the two phases of the doubt. His words, spoken not from Himself, are from the Father, and therefore He utters them from within the Father, and is Himself in the Father. His works are the works of the Father abiding in Him; therefore the Father is in Him.
