Jesus therefore answered them, "Most assuredly, I tell you, the Son can do nothing of himself, but what he sees the Father doing. For whatever things he does, these the Son also does likewise.
"The Father is witness of Me." When Jesus was baptized, God spoke from heaven and said, "This is My beloved Son in whom I'm well pleased." "The Father is born witness of Me." But Jesus wasn't referring to that, He was referring to the Old Testament scriptures. Where in the Old Testament, God bore witness of His Son who He would send into the world. "The Father hath born witness of Me."
