  • Theodicy — the attempt to understand how a good and powerful God can allow evil and suffering.
  • Worldview — the basic framework of beliefs through which a person interprets reality.
  • Presuppositional apologetics — an approach that begins from the truth of God and Scripture rather than arguing to it from neutral ground.
