Christians believe that while God is omnipotent (all-powerful) and wholly benevolent (all-good), evil still exists in the world. This poses difficulties in understanding the relationship between God's nature and the existence of evil. Christians respond in several ways: 1) Some suffering results from human sin and rebellion against God. 2) Innocent people may suffer due to the sins of others. 3) All humans suffer and experience hardship as a result of the original sin of Adam and Eve. 4) Satan tempts humans to sin and cause suffering. Overall, Christians believe humans are capable of both good and evil due to free will given by God and influenced by Satan.
