John 6:62-64

Amplified Bible, Classic Edition

⁶² What then [will be your reaction] if you should see the Son of Man ascending to [the place] where He was before?

⁶³ It is the Spirit Who gives life [He is the Life-giver]; the flesh conveys no benefit whatever [there is no profit in it]. The words (truths) that I have been speaking to you are spirit and life.

⁶⁴ But [still] some of you fail to believe and trust and have faith. For Jesus knew from the first who did not believe and had no faith and who would betray Him and be false to Him.
