Job
The Book of Job helps us to understand the following: Satan cannot bring financial and physical destruction upon us unless it is by God’s permission. God has power over what Satan can and cannot do. It is beyond our human ability to understand the “why’s” behind all the suffering in the world. The wicked will receive their just dues. We cannot always blame suffering and sin on our lifestyles. Suffering may sometimes be allowed in our lives to purify, test, teach, or strengthen the soul. God remains enough, and He deserves and requests our love and praise in all circumstances of life.
