Religious experiences can take several forms that draw people closer to God or provide evidence of God's existence. These include numinous experiences of feeling God's presence in nature, prayer which allows communication with God, miracles which seem to defy scientific laws, and conversion where one's life is changed by dedicating it to God. The most famous biblical example is the conversion of Saul to Paul, where Saul experienced a vision of Jesus that changed his life and led him to spread the word of Christianity. Religious experiences can strengthen belief in God by providing direct contact or evidence of God acting in the world.
