One question for Christians

[SavedByGraceThruFaith]

God is holy and must punish sin.

The Bible says that:
"the wages of sin is death" (Romans 3:23)

After death, comes judgment before God.

If the wages of sin is death, then why is there a need for judgment after one has paid for their sins? Wouldn't that be double jeopardy?

So the sacrifice of Jesus Christ is to pay for our sins, so those that trust Him as Saviour have all their sins, paid for and forgiven.

Jesus is a substitue to take our place. He pays fro our sins and gives everlasting life to those that believe.

That sounds like cheating. Christ doesn't sacrifice his life, he sacrifices a human body that he wore as a shell for a period of time that isn't even the blink of an eye for him compared to his time spent as a spirit being. Yet this cheap little "sacrifice" is sufficient to save every single soul that sins, if those humans (who stand to lose much more than a temporary throwaway existence) bend their knees to him.

And it's all because god "must" punish sin, apparently by passing judgment on the souls of people who already received their punishment for sin by dying. That doesn't make sense.

The punishment for sin is death.
But after death comes the judgment of where that person.
If saved then that person goes to heaven to be with Jesus Christ.

As to the crucifixion, it is hardly a small penalty.

Jesus, who never sinned, was beaten, mocked, spat upon, and the hairs of His beard pulled out. They put a crown of thorns on Him and beat it onto His head. His back was scourged repeatedly, tearing open His flesh. He carried a rough wooden cross to Calvary. They drove metal spikes into both of Christ’s hands and feet, crushing bone and into nerve tissue. Jesus then hung on that torturous cross for six hours. Our sins cost Christ that punishment. Yet Jesus endured all that unto death because of how much He loves you. Jesus had to endure all that to the end to save you.

But Jesus Christ, who never sinned and never had the guilt of sin, actually bore all sins and the guilt of all sins during the crucifixion. So this part may have been worse than the actual crucifixion. That is a tremendous amount of sin.
