Exodus 14:31 (NLT) When the people of Israel saw the mighty power that the LORD had unleashed against the Egyptians, they were filled with awe before him. They put their faith in the LORD and in his servant Moses. A lot of people today had once been in this state where they attest to God's might, but then they face another challenge and start doubting if God exists. They even go as far as saying there's no God but the past was a coincidence. The Isrealites did same too. Truth though is with or without these miracles, there is God who is Yahweh and He is supreme.
