That only resurrection justifies us, You argue it from the Law of Moses,
Only the resurrection. Just a byproduct of no importance to the atonement made by the Lamb of God.
The Lamb of God died for our sins by shedding His blood. He is risen to make atonement for our sins by sprinkling His blood, on them that repent of our sins that shed His blood..
That only resurrection justifies us, You argue it from the Law of Moses,
I argue any blood sacrifice and atonement under the OT, from the law of Moses. I don't argue for any blood sacrifice as God's, whose blood is only shed and not sprinkled.
And I certainly don't argue any definition of bleeding out, as a sprinkling unto death.
Killing the sacrifice is not the atonement. Sprinkling the blood makes the atonement.
Lev 1:4 And he shall put his hand upon the head of the burnt offering; and it shall be accepted for him to make atonement for him. And he shall kill the bullock before the LORD: and the priests, Aaron's sons, shall bring the blood, and sprinkle the blood round about upon the altar that is by the door of the tabernacle of the congregation.
Lev 17:11For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul.
The shed blood does not make atonement for anyone. It's only the blood sprinkled that makes the atonement for our souls.
The atonement is not made by the Lamb of God as that of bulls and goats. His blood was shed by man, but only He Himself sprinkles His blood by resurrection from the dead.
And only upon the obedient that repent of their sins and His death. He died for our sins to be repented of, He is raised again to atone for and justify them that do repent.
-NT theology does not explicitly identify the resurrection of Christ as the source of our forgiveness, atonement, and redemption.
Your theology doesn't. God's words do:
Rom 10:9That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
Your disdain for Jesus' resurrection as necessary to be saved, is by your own faith alone.
The NT of God is that of the resurrected Lord Jesus Christ, not the dead Jesus on a cross. Any NT without the resurrection of Jesus Christ certainly qualifies as another gospel, than that of Jesus Christ given to His apostles:
Gal 1:8But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.
The gospel of Jesus Christ is that of His death for our sins, buiral, and resurrection from the dead, that any man may now repent of our sins that killed Him, and recieve His atonement, mercy, and righteousness from lust and sin.
The dead Jesus on the cross, could not forgive any man on earth for killing Him.
It is the death of Christ, and the blood of Christ, that indeed identifies our sin and guilt, but which then recognizes at the same time our forgiveness, atonement, and redemption.
His death condemns the sins of all men, and judges all sinners guilty of His death at the cross. And a dead man recognizes nothing on earth.
The theology of beleiving in the death of Jesus Christ alone for forgiveness of sins, is trusting in a dead man to forgive us for killing Him.
There is no NT without the resurrection of Jesus Christ. There is no NT forgiveness on earth by the dead Jesus Christ.
The death of Christ on the cross is therefore the source of God's grace and mercy to us,
It's the source for God judging all men guilty of His innocent shed blood. The Jew first and also the Gentile.
because that is where our sins are fully pointed out and thus where we can escape its verdict.
No one on earth escaped that judgment of guilt at the cross, nor during the 3 days of His burial.
The resurrection certainly had to follow or the forgiveness we obtained at the cross would go to no value.
And so, we see the same preaching of all justification by faith alone, as being apart from works. If forgiveness is at the cross by faith alone in His death, then it cannot be with any repentance from dead works.
Only by His resurrection does Jesus now command all men everywhere to repent of His death.
Act 2:36 Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ. Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?
Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
Acts{3:19} Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord; {3:20} And he shall send Jesus Christ, which before was preached unto you:
These verses are called NT Scriptures, because they are written by God's apostles given them by the resurrected Jesus Christ.
Act 1 Until the day in which he was taken up, after that he through the Holy Ghost had given commandments unto the apostles whom he had chosen:
The commandments and promises of NT repentance and forgivness of sins are not written before His resurrection. They are only given and made after His resurrection, And certainly not while killing Him on a cross, nor while His dead body was in a tomb.
Only by His resurrection can Jesus Christ now atone for and forgive them that repent. Only by His resurrection can He now be sent into our hearts to convert us to His faith and righteousness. Only by His resurrection can the risen Lamb of God wash away our own faith of unrighteousness, which is dead by lust and unrighteous to God the Father.
