Why does God permit suffering?

When Satan led Adam and Eve into disobeying God, an important question was raised...the question of God's right to rule. A precedent needed to be set to show that Man cannot be better off without God’s rulership.

"I well know, O Jehovah, that to earthling man his way does not belong. It does not belong to man who is walking even to direct his step." (Jeremiah 10:23)

The Bible tells us that "God is love." (1 John 4:8) And the Bible shows that God hates wickedness and the suffering it causes far more than any human does. (Isaiah 55:8, 9)

So the Bible assures us that one day: "No resident will say: 'I am sick.'" Isaiah 33:24) The Scriptures also promise: "At that time the eyes of the blind ones will be opened, and the very ears of the deaf ones will be unstopped. At that time the lame one will climb up just as a stag does, and the tongue of the speechless one will cry out in gladness." (Isaiah 35:5, 6)

These, and many more Scriptures provide the divine promise that one day God will end the suffering in the world.
