Paradox #1
The contradiction or conflict might arise from the theme of divine retribution and justice. Some people may find it difficult to reconcile the idea of a loving and forgiving God with the idea of a God who also punishes and destroys as an act of justice. This could seem inconsistent with other teachings about forgiveness and mercy.
