No. The most common miracle hoped for by the faithful in modern times is a medical cure, however the experience of the Templeton Foundation casts strong doubt on whether God really does heal people, even in response to prayer.
Many Catholics hope for miracles, nearly always cancer cures, in response to prayers to proposed saints, so that the saint can be canonised by the Church. This has been described as an exercise in self-deception and even Catholic religious leaders have used the term "our delusions" in defending the practice against criticism.
