John 6: 35 And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.
John 6:40 And this is the will of him that sent me, that everyone which sees the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day…. After making it plain to them that it was eternal life, and a deep relationship with God he was offering to establish in their hearts, it became obvious that very many of them soon lost interest in Him. And according to the sacred record things reached a tipping point where most of them turned back from following Jesus, and their decision to turn their back on God was never afterward reversed.
John 6:66 From that time many of his disciples went back, and walked no more with him. 67 Then said Jesus unto the twelve, Will you also go away? However, some of them treasured their relationship with Christ more than any temporal blessings, and healing, and just as it was with Job, Caleb and David, it was forward ever, backward never….. John 6:68 Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life.
[The Desire of Ages pp 392] By the public rebuke of their unbelief these disciples were still further alienated from Jesus. They were greatly displeased, and wishing to wound the Savior and gratify the malice of the Pharisees, they turned their backs upon Him, and left Him with disdain. They had made their choice, had taken the form without the spirit, the husk without the kernel. Their decision was never afterward reversed; for they walked no more with Jesus.
John 6:69 And we believe and are sure that thou art that Christ, the Son of the living God.
May God add His blessing to the study of His word. “Good night” and God bless!
