In several passages I see that Jesus' sacrifice on the cross made atonement for our sins (Hebrews 2:17, 1 John 2:2, 4:10), and this is what we need to have faith in:
Romans 3:25: "God presented him as a sacrifice of atonement, through faith in his blood. He did this to demonstrate his justice, because in his forbearance he had left the sins committed beforehand unpunished--"
The above passage says that we need to have faith in Jesus' blood, and two chapters later Paul explained this more clearly:
Romans 5:8: "But God demonstrates his own love for us in this: While we were still sinners, Christ died for us."
Romans 5:9: "Since we have now been justified by his blood, how much more shall we be saved from God's wrath through him!"
Romans 5:10: "For if, when we were God's enemies, we were reconciled to him through the death of his Son, how much more, having been reconciled, shall we be saved through his life!"
I noticed that Paul referred to Jesus' blood in the context of His death. In the book of Colossians, Paul was even more specific:
Colossians 1:19: "For God was pleased to have all his fullness dwell in him,"
Colossians 1:20: "and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross."
Colossians 1:21: "Once you were alienated from God and were enemies in your minds because of your evil behavior."
Colossians 1:22: "But now he has reconciled you by Christ's physical body through death to present you holy in his sight, without blemish and free from accusation--"
In the above passage, Paul said that God has reconciled us to Himself through Jesus' blood which He shed on the cross, and then Paul added that we were reconciled by Jesus' physical body through His death.
So putting all of this together, when the Bible talks about Jesus' "blood" it's referring to His sacrificial death on the cross which made atonement for our sins and reconciled us to God.
In addition, another important point is that Jesus was resurrected from the dead. This demonstrated that Jesus is the Son of God, and His resurrection is so important that our faith would be futile and useless if He had not been resurrected.
Being the holiness of God required the death for sin and the sinless Son of God, Jesus was made to be sin for us, that is Jesus who knew no sin and he died for the sin of the world; Would it be correct to say that the righteousness of God,
is, that God the Father did not allow his Son who knew no sin to remain dead for the sin of the world but gave him grace through the resurrection of life by the Spirit of God?
What did Jesus mean when he told John in Matt. 3:15 YLT But Jesus answering said to him, `Suffer now, for thus it is becoming to us to fulfill all righteousness,' then he doth suffer him.
How was all righteousness fulfilled? What brought about the righteousness of God being made manifest?
Romans 5:9 YLT much more, then, having been declared righteous now in his (Jesus) blood, we shall be saved through him (Jesus) from the wrath; (Of God the Father)
And now apart from law hath
the righteousness of God been manifested, testified to by the law and the prophets, and
the righteousness of God through the faith of Jesus Christ to all, and upon all those believing, -- for there is no difference, Romans 3:21,22 YLT
It appears to me it was the faith
of Jesus Christ, his death, shed blood by which the righteousness of God could be made manifest.
It is the righteousness of God the Father that is imputed
to all and upon all the ones believing, through Jesus the Son of God, raised from the dead by God the Father. This is done by the, setting apart of, the sanctification of the Holy Spirit.
Is not all of this pictured in the water baptism of Jesus?
Will all who are saved have to be baptized with same baptism of which Jesus was baptized with in order to be saved? That is to inherit the kingdom of God?
That is to be changed from a flesh and blood temporary life being, to an quickened spirit being with eternal life, incorruptible?
