God died on the Cross.
It's a bit challenging for us in our way of thinking to accept some things without getting a little uneasy. Remember, it is the Muslims who claim that Jesus did not die on the Cross, but somehow appeared to die on the Cross. Some of them say it was a vision, but not real, other Mohammedans say that it looked like Jesus but wasn't really him, others say that someone took his place. They have various versions, but they come down to a denial of the Church's teaching, that God died on the Cross.
We have theologians who speculate that it was not absolutely necessary for Jesus to die on the Cross, for even one drop of his most precious Blood would be sufficient to redeem a thousand worlds. But that Jesus chose to suffer and die for our redemption, and this shows his infinite love for us, as it was something that he did out of free choice, and God's will.
God endured death on the Cross, and then, resurrected, shows us that he has conquered death, that we might learn this way that eternal salvation is victory over eternal death.
It is very popular these days for people to laugh at hell, or to pretend that it's not important. This is a huge accomplishment of the devil. How foolish it is for man to scoff at hell and refuse to believe the revelation of God, for it is only in this short lifetime that we have, when we can grow in grace, by doing penance and believing what we have been given at such a price, the blood of martyrs and of Jesus crucified. For once we have died, it's too late then, and we will face eternity with the consequence of our folly.
Now is the time of salvation!
