A.T. Robertson Commentary John 14:11

"Believe me that I am in the Father, and the Father in me: or else believe me for the very works` sake." — John 14:11 (ASV)

Believe me (πιστευετε μο). Repeated appeal (present active imperative of πιστευω) as in 14:1 to his disciples and as he had done with the hostile Jews to be influenced by his "works" at any rate (10:38).
