For Christ also suffered once for sins, the just for the unjust, that He might bring us[a] to God, being put to death in the flesh but made alive by the Spirit.
All the sacrifice and suffering of Jesus Christ until His death on the cross occurred once. It will not happen again physically or by a religious rite done by men. On the other hand, the passion of Christ is a unique, inimitable and unique event. Only the Son of God could serve as the sacrificial Lamb who takes away the sin of the world.
No other being, whether human or spiritual, can do what Jesus did. It is painful to see the image of Jesus that some people who envision Him as a poor skinny naked man hanging on a cross. This is an image of defeat, humiliation; but it is what most people imagine when they mention the name of Jesus. Certainly the crucifixion of Jesus Christ was an actual fact; but that happened once and He did not remain on the cross and His sacrifice is not repeated every day.
In Hebrews 9:27-28 we read: And as it is appointed for men to die once, but after this the judgment, so Christ was offered once to bear the sins of many. To those who eagerly wait for Him He will appear a second time, apart from sin, for salvation. What happened at Calvary two thousand years ago will not happen again and the second coming of Christ will be of no way equal to the first.
You have to understand very clearly the purpose of the two comings of Jesus Christ to Earth to understand that each one is different. The first coming of Christ was intended to reconcile sinful humanity with a just and good God. For all have sinned and the wages of sin is death, someone must die for the sins of all. But that someone must have been a perfect, unblemished and only Jesus fulfills that requirement.
Remember what John 1:1: In the beginning was the Word, and the Word was with God, and the Word was God. The Word is one of the many names by which Scripture identifies Jesus Christ, which can be determined by what John 1:14: And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth. Therefore, Jesus Christ has the same attributes of God.
The second coming of Jesus Christ is not that He might be crucified again but to reign in glory and power on Earth. The Apostle John described in Revelation 19:11-16: Now I saw heaven opened, and behold, a white horse. And He who sat on him was called Faithful and True, and in righteousness He judges and makes war. His eyes were like a flame of fire, and on His head were many crowns. He had a name written that no one knew except Himself. He was clothed with a robe dipped in blood, and His name is called The Word of God. And the armies in heaven, clothed in fine linen, white and clean, followed Him on white horses. Now out of His mouth goes a sharp sword, that with it He should strike the nations. And He Himself will rule them with a rod of iron. He Himself treads the winepress of the fierceness and wrath of Almighty God. And He has on His robe and on His thigh a name written: KING OF KINGS AND LORD OF LORDS. God bless you.
