Compare the issue I was referencing above (2/15/1986), 23 years ago:
Consequently, it was for "the life of the world"—the entire world of redeemable mankind—that Jesus gave his flesh. And "anyone" of the world of mankind who eats symbolically of that "bread," by showing faith in the redeeming power of Jesus’ sacrifice, may enter onto the way to everlasting life. Here, the "vast mixed company" that shared with the Israelites in eating the manna in the wilderness foreshadow the great crowd of Jesus’ "other sheep" who, along with the anointed remnant of "the Israel of God," are now eating Jesus’ flesh in a figurative sense. This they do by exercising faith in his sacrifice.—Galatians 6:16; Romans 10:9, 10.
Back in Galilee, many of Jesus’ listeners are shocked by his talk. So while still on the topic of his flesh, he even goes a step further, telling them: "Most truly I say to you, Unless you eat the flesh of the Son of man anddrinkhisblood, you have no life in yourselves. He that feeds on my flesh and drinks my blood has everlasting life, and I shall resurrect him at the last day; for my flesh is true food, and my blood is true drink." (John 6:53-55) Shocking indeed! Not only is the idea of cannibalism repulsive to those Jews but the Law at Leviticus 17:14 positively forbade eating "the blood of any sort of flesh."
Of course, Jesus is here emphasizing that anyone who is to attain to everlasting life must do so on the basis of exercising faith in the sacrifice that Jesus later made in offering up his perfect human body and pouring out his lifeblood. (Hebrews 10:5, 10; 1 Peter 1:18, 19; 2:24) This provision is not restricted to Jesus’ joint heirs. It must also include the "great crowd," who survive "the great tribulation," for these "have washed their robes and made them white in theblood of the Lamb." Their having faith in Jesus’ sacrifice, as demonstrated also by their rendering God "sacred service," results in their preservation through earth’s greatest time of distress. Similarly, Rahab was declared righteous and survived when Joshua devoted Jericho to destruction.—Revelation 7:9, 10, 14, 15; Joshua 6:16, 17; James 2:25.
