They're not presented as razzle 'em dazzle 'em magic tricks. They're not wheel of fortune-like, well at least someone wins big types of game show events. Miracles in the gospels are signs. Signs pointing to a new reality that is beginning to break through into a dark and desperate world. A new reality that revolves around Jesus.
Miracles are signs that point in two directions.
They point back to a time in Eden when physical bodies did not go blind, get crippled, or bleed non-stop for twelve years. They point to the way God originally meant life on earth to be. Some people see these miracles as implausible suspensions of the laws of the physical universe. They show that death, decay, entropy and destruction are the true suspensions of God's laws. These miracles are the early glimpses of restoration.
