"Say to the house of Israel, 'Thus says the Lord GOD: Behold, I will profane my sanctuary, the pride of your power, the delight of your eyes, and the yearning of your soul, and your sons and your daughters whom you left behind shall fall by the sword.'" Ezekiel 24.21
The Temple of Solomon was reduced to ashes and, in its place, the temple of Muhammad was erected. So the prophecy to the people who had once been the glory of the Lord was fulfilled. Why?
Because of pride.
Pride is the reason why many people fall. Especially those who once belonged to God.
