Note: for the significance of
"Eat My flesh and drink My blood"
please scroll down.
Jesus did not change an iota - as He said - of the Old Testament.
But to the ten commandments which He gave Moses, He added the two which basically include the ten:
Note again the symbolism: It is now 12 commandments, like the 12 tribes of Israel.
In short, the basics of Jesus‘ teaching:
God loves you. Love God above all by observing and acting according to His commandments
Love your neighbor like yourself
Your enemy is also your neighbor
Who sees Jesus Christ (God‘s wisdom) sees the Father (God‘s love) and the Holy Spirit (God‘s endless power).
Jesus came to earth as a model for all creation, to redeem mankind and to build a bridge to Himself (God).
Who believes in Jesus will not feel death, has eternal life and his sins, if stopped, will be forgiven.
Of all created souls in the universe only humans have a totally free will, meaning the privilege to freely decide between good and evil, God and Satan. If they pass the test they are entitled to become ‘Children of God‘. Only through life and death on earth can a soul achieve this state.
In order to become ‘Children of God‘, humans are invited to internalize His Word (‘eat Jesus` flesh‘) and perform active love towards God and fellow man (‘drink His blood‘) because for the human soul God‘s Word becomes the flesh and His Love its life-blood.
Eating Jesus‘ flesh and drinking His blood.
In Jesus‘ symbolic language flesh = bread = His Word, and blood = wine = His active love.
Thus: Reading/absorbing/believing the Word of God means eating the heavenly bread or His Flesh; acting lovingly and unselfishly towards God and the neighbor according to the Word means drinking the heavenly wine or His blood.
In GGJ.09/72 and 73 Jesus says:
"All life is, as it were, stimulated and awakened from without, but then it always comes into being, develops, unfolds, shapes itself and consolidates from within. Thus I, in My teaching to the people, am a true bread of life from the heavens, and the compliance with it is a true drink of life, the best and strongest wine which through its spirit enlivens the whole man and illumines him throughout through the brightly shining flame of his love-fire. Whoever eats this bread and drinks this wine, will no longer see, feel and taste death in eternity.
(09/73, 2 on) "For bread and flesh, like wine and blood, are one and the same, and whoever eats the bread of the heavens in My Word and drinks the wine of life through the compliance with the Word, namely, through the works of true, completely unselfish love for God and the fellowman, eats My flesh and drinks My blood. Like the way the natural bread is transformed into flesh and wine into blood by the body, within the soul of man My word-bread is transformed to the flesh and My love-wine of action to blood of the soul.
However, if I say ‘He who eats My flesh‘, this already means that he did not only store My Word in his memory and his intellect but also in his heart, which - as I already told you - is soul‘s stomach. The same goes for the love-wine of action which through that has become the blood of life. This because man‘s memory and intellect relate to the heart like the mouth to the natural stomach. As long as the natural bread is in the mouth it is not flesh but bread, but when it arrives after chewing in the stomach and is mixed with its digestive juices it is for its subtle parts already flesh because similar to flesh. The same can be said for the wine.(...)
Therefore, let none of you be only a hearer, but right away also an earnest and diligent doer of My word, and your soul will very soon be rid of all its scruples and doubts.
When you will fully possess My Kingdom within you, you will be able to walk on serpents and scorpions and drink poison out of hell without thereby ever suffering any injury. Now that you have well grasped and comprehended all this, you will also understand in the full and living truth what I wanted you to understand in Capernaum by the ‘eating of My flesh‘ and the ‘drinking of My blood‘, and will henceforth surely not call it a harsh precept.
