Jesus is perfect and Holy, without sin, but the wrath of God was taken out on Jesus when He died and paid for our sins, so when our sins went to Jesus, was Jesus a sinner at that time? How can one explain this
2Co_5:21 For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
Heb_9:26 For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.
Heb_9:28 So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.
I know 2Cor 5:21 has been posted before---but read it again. You must understand that it was more than sins that were placed on Him---He took upon Himself every single sin ever committed and He
WAS MADE SIN. On the cross, He was sin itself, the very essence of sin, every sin ever done by every person since Adam and Eve!! We who do not understand that, can not even begin to comprehend the suffering He endured. For as this happened, God the Father---who is too pure and holy to look upon sin---had to withdraw from the presence of Jesus.
Mat 27:45 Now from the sixth hour there was darkness over all the land unto the ninth hour.
When God withdrew, darkness came. God, who is light, was repelled by the sin that was now His Son.
It was this that broke the heart of Jesus, His Father had to withdraw from Him and that is when Jesus uttered
Mat_27:46 And about the ninth hour Jesus cried with a loud voice, saying, Eli, Eli, lama sabachthani? that is to say, My God, my God, why hast thou forsaken me?
This cry was wrenched from His very soul as He felt His Father, who had been with Him from everlasting, pull away. He was quoting from Psalm 22. No man killed Him, no Roman spear killed Him, it was not the wrath of God that killed Him---it was being absent from the presence of His Father, who is love itself. And His heart literally burst.
Joh 19:34 But one of the soldiers with a spear pierced his side, and forthwith came there out blood and water.
This only happens when the heart has ruptured and blood and water are released. Jesus was dead before the spear was thrown.
He had been sinless. Always was sinless, until the cross. At the cross, He had to rely on faith that His sacrifice would be accepted by God for He knew His Father was not there for now.
As to what happened to those sins He covered---one must look to the Day of Atonement to see---for on that Day once a year, 2 goats wer brought to the High Priest. One goat had all the sins of the congregation and the priest placed on it's head, representing Jesus---and that goat was slain by the priest and His blood sprinkled for the cleansing of the people and the sanctuary. The slain goat paid the price of sin---death---his blood covered the sins of all present. Then the High Priest placed His hands on the live Goat, thus transferring the sins from the slain goat, to the live goat. That goat was driven out into the dessert and set free---to die of starvation and thirst. The live goat represented Satan. It is he that is to blame for all sin, for the sins that Jesus had to pay for are all were transferred to him, and it is He that the blame for all sin will one day fall on.
Some say that the 2nd goat also represents Jesus---but Jesus died but once for sin, not twice. The blood of Jesus forgives and covers all sins---but the penalty of sin, permanent death, will be laid on the head of Satan and He dies the 2nd death and with him dies all sin.
Jesus allready paid the price for everyone's sins, but the person has to accept this in faith and follow Him. Without accepting the blood of Jesus then the sins are not covered and whoever dies without that blood will have to die the 2nd death with Satan and his fallen angels. The saved die but once---the lost die twice. We are rsurrected unto eternal life, the sinner resurrected unto eternal death.
