John 6:64-66

Amplified Bible, Classic Edition

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.

⁶⁶ After this, many of His disciples drew back (returned to their old associations) and no longer accompanied Him.
