John 6:37 All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out. 38 For I came down from heaven, not to do mine own will, but the will of him that sent me. 39 And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day. 40 And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
[The Desire Of Ages. pp 388>389] Christ became one flesh with us, in order that we might become one spirit with Him. It is by virtue of this union that we are to come forth from the grave,—not merely as a manifestation of the power of Christ, but because, through faith, His life has become ours. Those who see Christ in His true character, and receive Him into the heart, have everlasting life. It is through the Spirit that Christ dwells in us; and the Spirit of God, received into the heart by faith, is the beginning of the life eternal.
The people had referred Christ to the manna which their fathers ate in the wilderness, as if the furnishing of that food was a greater miracle than Jesus had performed; but He shows how meager was that gift when compared with the blessings He had come to bestow. The manna could sustain only this earthly existence; it did not prevent the approach of death, nor insure immortality; but the bread of heaven would nourish the soul unto everlasting life. The Savior said, “I am that bread of life. Your fathers did eat manna in the wilderness, and are dead. This is the bread which cometh down from heaven, that a man may eat thereof, and not die.
I am the living bread which came down from heaven: if any man eat of this bread, he shall live forever.” To this figure Christ now adds another. Only through dying could He impart life to men, and in the words that follow He points to His death as the means of salvation. He says, “The bread that I will give is My flesh, which I will give for the life of the world.” The Jews were about to celebrate the Passover at Jerusalem, in commemoration of the night of Israel's deliverance, when the destroying angel smote the homes of Egypt.
In the paschal lamb God desired them to behold the Lamb of God, and through the symbol receive Him who gave Himself for the life of the world. But the Jews had come to make the symbol all-important, while its significance was unnoticed. They discerned not the Lord's body. The same truth that was symbolized in the paschal service was taught in the words of Christ. But it was still undiscerned. Now the rabbis exclaimed angrily, “How can this Man give us His flesh to eat?” They affected to understand His words in the same literal sense as did Nicodemus when he asked, “How can a man be born when he is old?” John 3:4.
1st Corinthians 2:14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
May God add His blessing to the study of His word. "Good night" and God bless!
