Nevertheless, are we still going to believe in God?

If we believe in God, not because of Jesus but because of material blessing, 

the blessing of children, the blessing of health and so on that we want and expect from God,

Then God may allow Satan to take away all those blessings (Job 1:9-12).

Nevertheless, are we still going to worship God

Without committing the sin of blaming on God? (vv. 20-22)
