How do Christians use theodicy

A theodicy is an attempt to justify or defend God in the face of evil by answering the following problem, which in its most basic form involves these assumptions: God is all good and all powerful (and, therefore, all knowing). The universe/creation was made by God and/or exists in a contingent relationship to God.

The term literally means “justifying God.” Although many forms of theodicy have been proposed, some Christian thinkers have rejected as impious any attempt to fathom God's purposes or to judge God's actions by human standards.
