Why all the pain? In a nutshell.. It's because of man's sin.... It is man who want's war... It is man who wants evil... G-d can't do much until we turn to back Him. He did not create robots. Man must be willing to submit to His authority in order to preserve life..Empty Lord wrote:"God loves you" If so, whence come pain, sorrow and evil? For all who preach here, I give you Epicurus
"Is God willing to prevent evil, but not able? Then he is not omnipotent. Is he able, but not willing? Then he is wicked. Is he both able and willing? Then whence cometh evil? Is he neither able nor willing? Then why call him God?"
"But God gave humans free will" If God is omnipotent, it knows all motion of all matter, therefore it knows our future, leading to the conclusion God created all motion and future. Therefore any pain and suffering caused is a direct cause from God.
Want to stop evil in this world? Then stop sinning....
As written by the prophets..
Hosea 4:1-3
1 Hear the word of the LORD, you people, because the LORD has a charge to bring against you who live in the land:“There is no faithfulness, no love, no acknowledgment of God in the land. 2 There is only cursing, lying and murder, stealing and adultery, they break all bounds, and bloodshed follows bloodshed. 3 Because of this the land dries up, and all who live in it waste away; the beasts of the field, the birds in the sky and the fish in the sea are swept away.
