A.T. Robertson Commentary John 14:10

"Believest thou not that I am in the Father, and the Father in me? the words that I say unto you I speak not from myself: but the Father abiding in me doeth his works." — John 14:10 (ASV)

Believest thou not? (ου πιστευεισ; ). Jesus had a right to expect greater faith from these men than from the blind man (9:35) or Martha (11:27). His words in 14:1 are clearly needed. This oneness with the Father Jesus had already stated (10:38) as shown by his "words" (ρηματα) and his "works" (εργα). Cf. 3:34; 5:19; 6:62.
