The fourth past tense action is, “I have drunk my wine with my milk.” The Beloved had “wine with my milk,” or with strength and nourishment. Wine, not in excess, maketh the heart glad. In figurative language, the Beloved is describing the joy and fulfillment of the entire experience of consummation with his Bride. The joy was undergirded by that which sustains life in a newborn. A symbol of life and nourishment; it speaks of true joy and happiness.
In the spiritual sense, Christ is revealing the joy of fellowship in the Milk of His Word (1 Peter 2:2). The Joy of the Lord is in Himself, the Living Word of God; Who is God Himself (John 1:1-3). It brings Christ delight to see the works of faith in His Bride; the works which flow from the Word Himself (or The Faith) living and abiding in the believer.
Not only have I, Christ, eaten; but I have drunk My wine with My milk. I am full of My Glory; full of My Perfection, Preeminence, and Power. I am full of My Joy.
The entire scene here (Song of Solomon 5:1) is that of a time of rejoicing; a time of the husband and wife in the banqueting house; a time of love and communion of the highest order. This is a time of reaping the harvest of the tilling of the ground, the preparing of the broken ground; sowing the seed; tending to the plant; and now the reaping of the harvest. It is a time of joy, happiness, satisfaction, and completeness; a time of consummation between husband and wife.
Spiritually, it is when Christ enjoys the fruit of His Labors of Grace produced in His Children by the Power of God. The Children are full of Christ’s Presence, as they are allowed to behold His Glory, to be filled with His Spirit. It is a time of rejoicing in the Liberty of Salvation in Christ.
Next, the Beloved shifts to the present tense, “eat, O friends.” The Beloved commands the friends of the Bride to eat; to partake of the time of rejoicing.
This is better understood in the spiritual sense, as Christ calls His servants, “friends”:
“Henceforth I call you not servants; for the servant knoweth not what his lord doeth: but I have called you friends; for all things that I have heard of my Father I have made known unto you.” (John 15:15).
He is commanding His Bride to eat also, to partake, as He is the Food of God, the hidden Manna. Even eat of Me; eat My flesh and drink My blood. Rejoice in Me and in all that I am. For I am God; your Creator, Controller, and Consummator. I am your Savior and your All in All.
Then, in closing this scene of rejoicing, the Bride replies to her Beloved, “drink, yea, drink abundantly, O beloved.” Here the Bride is ecstatic; she is at the peak of his love. She is giving all of herself (body, soul, and spirit) to her Beloved. “Drink abundantly” she says, I am yours and you are mine. I am for you to enjoy. I am the work of your teaching and leadership.
In the spiritual sense of Christ and His Bride; the Church (the Bride) is saying to Christ, her Head, her Husband, her Beloved, “drink, yea, drink abundantly, O beloved.” That is, come to me and enjoy the fruit of Your Election and Atonement of me. Come and enjoy the fruit of Your Holiness and Perfection; of Your Glory and of Your Love. Come and enjoy Your Purchased Possession, Your Dwelling Place, Your Prepared Place.
