What is the significance of miracles in the Bible?

In the Bible, there are many instances of miracles. Miracles can be defined in the Bible as acts performed by God or persons that run contrary to nature or physics. Examples of miracles in the Bible are the creation of the material universe by God out of nothing, (Genesis chapters 1 and 2,) The parting of the Red Sea by the Prophet Moses, (Exodus chapter 14:21–22,) and Jesus Christ walking on top of the Sea of Galilee, found in Matthew chapter 14:22–34, Mark chapter 6:45–53, and John chapter 6:15–21. In the book of Matthew, the Apostle Peter walked on water as well after being reassured by Jesus. The Bible encourages faith in its teachings by asserting that acts such as these actually took place. These assertions are made to the reader to emphasize that the Holy Trinity, namely God, Jesus Christ, and the Holy Spirit are Lord and Master over all things both physical and spiritual, and are able, through divine providence to nullify the effects of nature, and that nature itself obeys them. Miracles to me, are Biblical indicators that human knowledge and intelligence regarding the material universe are insufficient in relation to God’s divine intelligence and authority. The Psalmist King David proclaims in the book of Psalms Chapter 100:3, to “Know ye that the LORD he is God: it is he that hath made us, and not we ourselves; we are his people, and the sheep of his pasture.
