Isaiah 53:3 He was despised and rejected by mankind, a man of suffering, and familiar with pain. Like one from whom people hide their faces he was despised, and we held him in low esteem. 4 Surely he took up our pain and bore our suffering, yet we considered him punished by God, stricken by him, and afflicted. 5 But he was pierced for our transgressions, he was crushed for our iniquities; the punishment that brought us peace was on him, and by his wounds we are healed.
Who? Yehoshua (Jesus). He is God's Kingdom representative. Why is God pleased to crush His Son? Why does God let the human nations crush the Kingdom of God? It is because they are not of this world. To allow the Kingdom and the King to be crushed proves the Kingdom's sovereingnty rules beyond the life we know. The Kingdom with it's King Jesus was never crushed out of existance. It is always present. It has not become manifest on Earth because all have sinned. There is no one righteous. Where there is no one righteous, all are the same.
Cults are for taking people out of the truth of God's sovereingnty where all are the same to where they are different. They say the way they are different is they are the only ones who will be saved. That is the power of a cult. They claim salvation is theirs alone.
