5 A testimony for the Head; “To Abraham and his seed were the promises made. He says not, And to seeds, as of many, but as of one, And to your seed, which is Christ.” A testimony for the body unto Abraham, which the Apostle has brought forward. “To Abraham were the promises made. As I live, says the Lord, I swear by Myself, because you have obeyed My Voice, and hast not spared your own beloved son for Me, that in blessing I will bless you, and in multiplying I will multiply your seed as the stars of heaven, and as the sand of the sea, and in your seed shall all nations of the earth be blessed.” You have here a testimony for the Head, and one for the Body.
Hear another, short, and almost in one sentence including a testimony for the Head and for the Body. The Psalm was speaking of the Resurrection of Christ; “Be Thou exalted, O God, above the heavens.” And immediately for the Body; “And Your glory above all the earth.” Hear a testimony for the Head; “They dug My Hands and My Feet, they numbered all My Bones; and they looked and stared upon Me; they divided My garments among them, and cast lots upon My vesture.” Hear immediately a testimony for the Body, a few words after, “All the ends of the world shall remember themselves and be turned unto the Lord, and all the kindreds of the nations shall worship in His sight; for the kingdom is the Lord's, and He shall have dominion over the nations.” Hear for the Head; And “He is as a bridegroom coming forth out of His bride-chamber.” And in this same Psalm hear for the Body; “Their sound went out into all the earth, and their words unto the ends of the world.”
