Juan 6:56

Because Jesus’ person is what truly satisfies and sustains life those who believe in Him remain (Gr. meno, abide) in Him. This is a new term in the discussion, but it is synonymous with having eternal life. Jesus was saying that believers continue to possess eternal life; they will never lose it. Believers remain in Christ, and He remains in them. Jesus was not speaking here to His disciples about the importance of believers abiding in fellowship with God as He did in chapter 15. Here He was speaking to unbelievers about entering into a saving relationship with God.
