Job still maintains his integrity, even be ruined without any reason

Job 2:1-13
Job still maintains his integrity, though Satan incited God against Job to ruin him without any reason.
Job replied, "You are talking like a foolish woman. Shall we accept good from God, and not trouble?" In all this, Job did not sin in what he said.
Satan has lost the first round. Now he says Job is only really concerned for his own skin. So God allows a further test, stopping short only at Job's life.
Job's body breaks out in running sores. The great man becomes an outcast. His wife fails him. The three friends who remain loyal sit in silence, appalled at what has happened. But still Job holds fast to God.
Ashes are linked with suffering, mourning and humble repentance.
Why?
Calamities beset Job like a whirling dust storm. This is the time of testing.
God is the sovereign Lord, he gives us blessing and troubles. The trouble is test to confirm our faith to him.
My life, my possession and joy are the blessing and gifts from the Lord. I am his servant in God's pastureland.
Tested the good of God, then I will not forsake the Lord!
How?
God has set me free from sins and I will be spiritual free at all.
