Anytime you hear a news report or someone say that the muslim war cry means ‘God is great,’ be sure to correct them. It means ‘allah is greater.‘ And if you don’t know who wanted to be greater than God, here’s some Scripture –
Thy pride is brought down to hell, thy carcass is fallen down: under thee shall the moth be strewed, and worms shall be thy covering. How art thou fallen from heaven, O Lucifer, who didst rise in the morning? how art thou fallen to the earth, that didst wound the nations? And thou saidst in thy heart: I will ascend into heaven, I will exalt my throne above the stars of God, I will sit in the mountain of the covenant, in the sides of the north. I will ascend above the height of the clouds, I will be like the most High. But yet thou shalt be brought down to hell, into the depth of the pit.
– Isaiah 14:11-15
