The problem of evil has been called the Achilles heel of Theism – it is the argument that requires the greatest amount of defense and explanation. This is the enigmatic question of, “how can an all-powerful, all-good, God coexist in a world where evil exists?” Anyone who has been faced with a tragic loss or unprovoked misfortune has asked this question in some form or another. Many skeptics have rejected theism for this very reason, and many Christians have turned from the Faith due to inability to rectify this paradox. While this seems to be an unanswerable question, many have attempted to justify God and offer an explanation.
Theism simply means, “belief in God.” The Theist is an individual who bases his life on the presupposition that there is a God and lives according to the implications that such a belief contributes to the world in which he lives. Conversely, an atheist is one who does not believe in God and lives his life with the implications of this worldview. Another opponent to theism is agnosticism, which derived from the Greek word “γνωστός” (gnostos) meaning known – agnosticism objects that knowledge of a deity cannot be confirmed or denied. While atheism and agnosticism have become prominent teachings in society today, they base their foundations on rather weak arguments that do not stand the test of logical consideration. Theism is a “first truth” meaning that it is universal (applicable to all cultures and periods of time), necessary (it must exist), independent (does not depend on being taught). This reality serves as an unshakable foundation for the theistic argument.

Definition of Theology
The most basic definition of Theology is, “The study or Science of God.” However, this casts a rather cold and impersonal shadow on a discipline that is intended to draw us nearer to God. As was stated prior, theology is unlike other sciences in that the ultimate goal is not to toil over facts and figures – meaningless rhetoric – but rather to find a real and living God who loves the seeker and has provided a plan for his redemption. Other studies are intended to enable the student to understand the subject better; theology is meant to enable to student to better know the Subject. Of course, theology can be minimized to a tiresome practice that deadens the passion of the individual, but this is the fault of the theologian, not theology. The life of the discipline is found in the subject matter - once extracted it brings one face to face with its implications. All that is left at that point is rejection of the truth or acceptance of a full life.
