ACTS BIBLE
A bonus study across the whole Bible
The covenant runs one direction, from the Father to His children, and the return direction exists in one person. The Son is the Apostle sent out from God and the High Priest who goes in to God, and every promise finds its answering yes in Him.
Every reference below was read in place in this site's own Bible text. Genesis 15 is the spine: the covenant is cut while Abram sleeps, and one party walks between the pieces.
Abram asks how he can know the land will be his: "Whereby shall I know that I shall inherit it?" (Genesis 15:8). The answer is a ceremony. Animals are divided and laid in halves, and in the ancient form both parties walked the path between them, each saying in effect, may this be done to me if I break my word. The form assumes two walkers.
Then the ceremony departs from its form. "A deep sleep fell upon Abram; and, lo, an horror of great darkness fell upon him" (Genesis 15:12). When the covenant is cut, "a smoking furnace, and a burning lamp that passed between those pieces" (Genesis 15:17). One party walks. Abram contributes sleep and darkness, and the oath's whole weight rests on the walker.
The believing had already happened: "he believed in the LORD; and he counted it to him for righteousness" (Genesis 15:6). The ceremony does not purchase the promise. It answers the question how shall I know, and the answer is that God alone carries the penalty clause.
At Bethel, God speaks to a fugitive who has just cheated his way out of his father's house: "I am with thee, and will keep thee in all places whither thou goest" (Genesis 28:15). The speech carries promise after promise and no conditions. Jacob answers with a vow that is nothing but conditions, "If God will be with me" (Genesis 28:20), and God neither corrects the terms nor renegotiates. The promise stands on the speech, never on the vow.
At Sinai, the people cannot survive the voice and ask for a man to stand between: "Go thou near, and hear all that the LORD our God shall say" (Deuteronomy 5:27). God's verdict on the request is approval: "They have well said all that they have spoken" (Deuteronomy 5:28). From its first hour the covenant's terms arrive through a mediator, a man standing between God and the people, because arriving any other way would kill the party receiving them.
At Shechem, Joshua renews the covenant over a warning: "Ye cannot serve the LORD: for he is an holy God" (Joshua 24:19). The people swear anyway, and Joshua sets up a stone that "shall be a witness" (Joshua 24:27). A covenant is renewed across the announcement that the human party cannot keep it, and the evidence for the coming breach is placed in the ground the same afternoon.
When the breach comes, Scripture assigns it. The covenant made at the exodus was the one "which my covenant they brake" (Jeremiah 31:32). Nothing in the record says God failed a clause.
The promised repair is written accordingly. In the new covenant every clause is spoken in one voice: "I will put my law in their inward parts" (Jeremiah 31:33), and "I will forgive their iniquity" (Jeremiah 31:34). A covenant broken from the human side is replaced by a covenant with no human clause in it.
Hebrews states why the security sits where it sits. When God made promise to Abraham, "because he could sware by no greater, he sware by himself" (Hebrews 6:13), and the heirs of promise received "two immutable things" (Hebrews 6:18), the promise and the oath, both His. There was never a second party strong enough to hold up an end.
One verse holds both directions as offices: "consider the Apostle and High Priest of our profession, Christ Jesus" (Hebrews 3:1). An apostle is sent out from God to men. A high priest goes in to God for men. The outbound office and the return office meet in one man, and Scripture never assigns the pair to anyone else.
Paul states the mechanism: "For all the promises of God in him are yea, and in him Amen" (2 Corinthians 1:20). The promises travel out from God. The Amen, the answering yes the covenant lacked from the human side since Eden, travels back in Him.
In Gethsemane, under the full weight of what the words would cost, the Son speaks the sentence no other man finished: "not my will, but thine, be done" (Luke 22:42).
"By so much was Jesus made a surety of a better testament" (Hebrews 7:22). A surety is the man who answers for another's debt when the other cannot pay. The covenant gains a guarantor, and the guarantor stands on the side that always failed.
The guarantee is a life. Christ lived the perfect life no sinner has lived, died under the sentence the broken covenant carried, and rose. The payment was not promised. It was made, and the resurrection is the receipt.
Psalm 89 sings the oath, "Once have I sworn by my holiness that I will not lie unto David" (Psalms 89:35), and then reports the crown profaned in the dust and asks where the sworn mercies went. The psalm ends without an answer. The answer is a son of David who died and did not stay dead, in whom "his seed shall endure for ever" (Psalms 89:36) came true and stays true.
The one direction runs through the giving of persons. The Son prays, "thine they were, and thou gavest them me" (John 17:6), and draws the line out loud: "I pray not for the world, but for them which thou hast given me" (John 17:9). The Father gives a people to the Son the same way He gives everything else in the covenant, by His own decision, not in answer to any request.
Revelation grounds the Son's right to those names in the purchase: "thou wast slain, and hast redeemed us to God by thy blood" (Revelation 5:9). The register of the redeemed is the Lamb's book of life, and the text speaks of names "not written in the book of life of the Lamb slain from the foundation of the world" (Revelation 13:8), and of what follows for "whosoever was not found written" (Revelation 20:15). If every name were in the book, the book would have nothing to do.
The writing is dated from the foundation of the world, before any name had done anything, and the news of it reaches a man as news: "rejoice, because your names are written in heaven" (Luke 10:20). Written already, by another hand, announced to the ones written.
A covenant resting anywhere on the human party has nothing to correct it when that party fails, and every chapter above records the failure arriving on schedule. This covenant rests on an oath sworn by the greater party and on a resurrection that shows the surety's payment was accepted.
The commands still stand. The covenant commands as surely as it gives, and the obedience it commands is costly: "let him deny himself, and take up his cross daily, and follow me" (Luke 9:23). But the commands follow the gift rather than funding it, and the faith that answers them is itself given, which is the argument of the study Faith Given, Commands Kept beside this one. The covenant that supplies its own return direction also supplies the faith that receives it.
A believer's assurance was never his own grip on the covenant. It is the covenant's grip on him, held in the Son who carries both directions, whose Amen answers for every name in the book.
