Look at the vs. before it (Deu.21:22.) Only people who committed a capital offense could be executed by Moses' law.
Yes, exactly. An offense such as blasphemy.
That putting an innocent man to death is sin, whether you're aware of it or not.
Of course.
Act.4:24-28. He said this because they were being threatened. The religious leaders were "gathered together against them", as they were "gathered together against the Lord and his Annointed" Opposed to God and Christ.
Again, how is this relevant? Look at the context:
Act 4:24 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,
...
Act 4:27 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,
Act 4:28
to do whatever your hand and your plan had predestined to take place. (ESV)
This passage is clearly showing that Jesus's crucifixion was planned and predestined to take place by God.
Act 2:23 this Jesus,
delivered up according to the definite plan and foreknowledge of God, you crucified and killed by the hands of lawless men. (ESV)
The whole thing--being "delivered up" to be "crucified and killed by the hands of lawless men"--was "according to the definite plan and foreknowledge of God."
It was Gods'plan to show mercy to wicked men who sinned by crucifying his Son, instead of doing what the law says should have been dine to them,
If a malicious witness takes the stand to accuse someone of a crime...and if the witness proves to be a liar, giving false testimony against a fellow Israelite, then do to the false witness as that witness intended to do to the other party...
Deu.19:16,18-19
Our Savior didn't use this statute against them. He erased it in mercy.
But how and what made it possible? God's holiness demands payment for sin. If God simply let them go without payment for breaking the law, then God is unjust. Either every sinner will bear the punishment of their sin, in hell for eternity, or they repent and believe that Christ's death atoned for their sin, and so are reconciled to God. That is the only way to get go free, to have our sins erased.
Rom 5:8 but God shows his love for us in that while we were still sinners,
Christ died for us.
Rom 5:9 Since, therefore,
we have now been justified by his blood, much more shall we be saved by him from the wrath of God.
Rom 5:10 For if while we were enemies
we were reconciled to God by the death of his Son, much more,
now that we are reconciled, shall we be saved by his life.
Rom 5:11 More than that, we also rejoice in God through our Lord Jesus Christ,
through whom we have now received reconciliation.
Rom 5:12 Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned—
…
Rom 5:15 But the free gift is not like the trespass. For if many died through one man's trespass, much more have
the grace of God and the free gift by the grace of that one man Jesus Christ abounded for many.
Rom 5:16 And the free gift is not like the result of that one man's sin. For the judgment following one trespass brought condemnation, but
the free gift following many trespasses brought justification.
Rom 5:17 For if, because of one man's trespass, death reigned through that one man,
much more will those who receive the abundance of grace and the free gift of righteousness reign in life through the one man Jesus Christ. (ESV)
I, even I, am He who comforts you.
Who are you that you should be afraid
Of a man who will die, And of the son of a man who will be made like grass? Isa.51:12
And many people shall go and say, Come ye, and let us go up to the mountain of the LORD, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the LORD from Jerusalem. Isa.2:3
Let not your heart be troubled: ye believe in God, believe also in me. Jn.14:1
I don't see how any of those verses state that the Messiah will teach everyone to not be afraid. How would that be relevant to his death?
Not the whole point. The whole point is, Moses' law and the prophets only condems sinners,
Yes, but as Paul points out:
Rom 3:23 for all have sinned and fall short of the glory of God,
But more than that, look at that statement in context:
Rom 3:21 But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it—
Rom 3:22 the righteousness of God
through faith in Jesus Christ for all who believe. For there is no distinction:
Rom 3:23 for all have sinned and fall short of the glory of God,
Rom 3:24 and
are justified by his grace as a gift, through the redemption that is in Christ Jesus,
Rom 3:25
whom God put forward as a propitiation by his blood, to be received by faith. This was to show God's righteousness, because in his divine forbearance he had passed over former sins.
Rom 3:26 It was to show his righteousness at the present time,
so that he might be just and the justifier of the one who has faith in Jesus. (ESV)
Even Jesus said that the default position is eternity apart from God, that only faith in his name would save:
Joh 3:16 “For God so loved the world,
that he gave his only Son, that whoever believes in him should not perish but have eternal life.
Joh 3:17 For
God did not send his Son into the world to condemn the world, but in order that the world might be saved through him.
Joh 3:18 Whoever believes in him is not condemned, but
whoever does not believe is condemned already, because he has not believed in the name of the only Son of God. (ESV)
We clearly see that God, the Father, sent the Son into the world "in order that the world might be saved through him." How was that done? What made that possible?
Rom 8:32
He who did not spare his own Son but gave him up for us all, how will he not also with him graciously give us all things? (ESV)
2Co 5:14 For the love of Christ controls us, because we have concluded this: that
one has died for all, therefore all have died;
2Co 5:15 and
he died for all, that those who live might no longer live for themselves but for him who for their sake died and was raised.
…
2Co 5:21
For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God. (ESV)
Gal 2:20 I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God,
who loved me and gave himself for me. (ESV)
The fathers shall not be put to death for the children, neither shall the children be put to death for the fathers: every man shall be put to death for his own sin. Deu.24:16
The soul that sinneth, it shall die. The son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son: the righteousness of the righteous shall be upon him, and the wickedness of the wicked shall be upon him. Eze.18:20
Okay. What do these have to do with the discussion, with Christ's death?
By repent(ance) and baptism.
Repent;
μετανοέω metanoéō, met-an-o-eh'-o; from
G3326 and
G3539;
to think differently or afterwards, i.e. reconsider (morally, feel compunction):—repent.
Baptism is symbolic of the death,
as many as have been baptised unto Christ Jesus, have been baptised unto his death Rom.6:3
But what makes repentance and baptism effective for the forgiveness of sins? John the baptist preached repentance and baptism, but not only was no one saved by that, he said Jesus was "the Lamb of God, who takes away the sin of the world!" (John 1:29). Why would John say that? What did Jesus's death accomplish if all that was needed was repentance and baptism?
