Jesus was mocked and horribly tortured before he died in a bloodbath on display for all including a His mother to watch; all the apostles except St John were horribly killed, skinned alive, burned alive, chopped up, crushed to death; early Christians were persecuted, families fed and eaten alive by wild beasts or used as human torches for entertainment. Understand that this world belongs to Satan, but it is the light of God that shines through the souls of those who follow the path forged by Jesus Christ for us to follow, a path that always involves the cross.
That the human soul is made in the image and likeness of God means that it is eternal and will exist forever. Thus this brief time on earth is a period of transition which gives a soul the means to gain merit in the Kingdom of God. In the end, the soul of each human being will usher into either the Kingdom of God, or the kingdom of Satan —depending on how one lives their life on earth.
The path that leads to God always involves some sort of suffering which is part of the process of sanctification; and sometimes it takes a great suffering in order for some souls to turn to God. The real question is why does God permit suffering? Suffering is the consequence of Original Sin, yet God brings good out of the suffering when we follow Christ.
Look up at the sky at night. The earth is a tiny piece if dust compared to the hundreds of billions of galaxies which make up the cosmos. The purpose of the earth is to act as a womb, as a place to harvest souls who will inherit the eternal infinite Kingdom of God; thus Jesus’ death and resurrection are a preview of what awaits those who love God: One needs a spiritualized glorified body in order to experience the kingdom that God has prepared for those who love a Him. Thus the Church teaches that one of the Four Qualities of the risen glorified body is
Agility—as Aquinas explained, the glorified body will obey the soul with the greatest ease as our Resurrected Lord’s ability to bilocate and travel great distances in an instant with the speed of thought. Even the worst suffering will be forgotten the instant one enters heaven. This video touches on that:
