John 6:63-65

Amplified Bible, Classic Edition

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.

⁶⁵ And He said, This is why I told you that no one can come to Me unless it is granted him [unless he is enabled to do so] by the Father.
