And when they heard it, they lifted their voices together to God and said, "Sovereign Lord, who made the heaven and the earth and the sea and everything in them, who through the mouth of our father David, your servant, said by the Holy Spirit, "'Why did the Gentiles rage, and the peoples plot in vain? The kings of the earth set themselves, and the rulers were gathered together, against the Lord and against his Anointed'--for truly in this city there were gathered together against your holy servant Jesus, whom you anointed, both Herod and Pontius Pilate, along with the Gentiles and the peoples of Israel, to do whatever your hand and your plan had predestined to take place. And now, Lord, look upon their threats and grant to your servants to continue to speak your word with all boldness.In this text, you have an affirmation of 1) absolute sovereignty, 2) the prophetic word, that will not be altered; 3) and the fulfillment of that word which is predestined to take place.
Peter says a similar word on Pentecost, Act.2:22-23
"Men of Israel, hear these words: Jesus of Nazareth, a man attested to you by God with mighty works and wonders and signs that God did through him in your midst, as you yourselves know--this Jesus, delivered up according to the definite plan and foreknowledge of God, you crucified and killed by the hands of lawless men.Again, Peter declares that none of these things has happened by accident, everything was prophesied, and the will of God for our salvation was accomplished through the lawless acts, but against the unrighteous intentions, of wicked men. Christ's crucifixion was according to the definite plan of God. The fact that it is also according to his "foreknowledge" doesn't modify that plan at all--it strongly affirms that what is determined by the will of God: he "sees to it" before it even happens in history.
To these testimonies of the apostolic church, we should also add Jesus' own repeated statements that he was going to Jerusalem in order to be killed, and to rise again. The angel announcing his birth said he was coming to save his people from their sins. Simeon prophesied to Mary with baby Jesus in his arms that a sword would pierce her heart over this Son's destiny. John the Baptist points to Jesus, before his ministry barely begins, saying, "Behold the Lamb of God, who takes away the sin of the world." This has reference to all the dying sacrificial lambs on the altar of Israel for centuries; and to the ram of substitution on the Mt.Moriah when the Lord stays the (obedient!) knife of Abraham; and to the expectations of a certain lamb spoken of by Isaiah, 53:6-7.
Jesus, on the road to Emmaus said to those disciples, Lk.24:25-27
And he said to them, "O foolish ones, and slow of heart to believe all that the prophets have spoken! Was it not necessary that the Christ should suffer these things and enter into his glory?" And beginning with Moses and all the Prophets, he interpreted to them in all the Scriptures the things concerning himself.
So confirm the apostles, Heb 2:10-11
For it was fitting that he, for whom and by whom all things exist, in bringing many sons to glory, should make the founder of their salvation perfect through suffering. For he who sanctifies and those who are sanctified are all of one."Act 17:1-3
Now when they had passed through Amphipolis and Apollonia, they came to Thessalonica, where there was a synagogue of the Jews. And Paul went in, as was his custom, and on three Sabbath days he reasoned with them from the Scriptures, explaining and proving that it was necessary for the Christ to suffer and to rise from the dead, and saying, "This Jesus, whom I proclaim to you, is the Christ."
Over and over, the apostles affirm that the death of Christ was necessary, planned, prophesied, and performed. Sin must be punished. It must be shown for what it is, and there exists no better method for showing it than that sinners attack and kill their God-Incarnate, their Emmanuel. But by this infinitely heinous act, God subverts their evil--their worst shall be his best, and only, help for them.
When they acknowledge their sin, their need for a Savior, but also their being total undeserving of salvation--then it becomes available to them, when they submit to God's design.
Be it known unto you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even by him doth this man stand here before you whole. This is the "stone which was set at nought of you builders, which is become the head of the corner" (Ps.118:22). Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.Act.4:10-12
