[Jhn 6:44 KJV] 44 No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.
[Jhn 6:45 KJV] 45 It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me.
From that time many of His disciples went back and walked with Him no more.
These disciples who came to Him, being drawn by the Father, did turn away from Him and followed Him no more.
Being drawn to His does not = eternal salvation.
Eternal salvation is for those who obey Him.
And having been perfected, He became the author of eternal salvation to all who obey Him. Hebrews 5:9
