The Bible tells us how evil was caused by the fall into sin of an angel, who became Satan or the devil. This angel chose to oppose God out of his own free will, and rejected God’s love. The devil can do a great deal of harm, but he remains a creature. Therefore, his power is not infinite. He cannot stop the coming of God’s kingdom.
Only God knows why he allows the evil work of the devil to continue, and why evil still exists in the world. However, we have been promised that in all things God works for the good of those who love him (Rom. 8:28).
