God is love.

To be affected by seeming anger is the failure to realize that God is omnipotent, else we could not be affected.  Anger is a human emotion felt when we feel threatened or cheated or misunderstood.  With the realization that God is our life, our very being, and that also of others, anything unlike God and unlike His love is seen as nothingness.  With anger seen for what it is, impersonal attachment to something in this "world", it has no power and cannot touch us.
