Who is starving
57 As the living Father hath sent me, and I live by the Father: so he that eateth me, even he shall live by me.
58 This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live for ever.
Amen!
John 6:40 - Everyone who looks to the Son and believes in Him may have everlasting life; and I will raise him up at the last day.
John 6:54 - Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day.
John 6:47 - Most assuredly, I say to you, he who believes in Me has everlasting life.
John 6:58 - He who eats this bread will live forever.
"He who believes" in Christ is equivalent to "he who eats this bread and drinks My blood," because the result is the same, eternal life. Jesus is the Bread of Life and believers eat of Him and are satisfied unto everlasting life. :)
Bread represents the "staff of life." Sustenance. That which essential to sustain life. Just as bread or sustenance is necessary to maintain physical life, Jesus is all the sustenance necessary for spiritual life. The source of physical life is blood -- "life is in the blood." As with the bread, just as blood is the empowering or source of life physically, Jesus is all the source of spiritual life necessary.
