There are many miracles in the bible but no miracle made anyone have faith; when the Israelites were about to enter the promised land they didn't have enough faith even though they should have been the ones who KNEW God was on their side, they witnessed the parting of the red sea, God provided mana for them yet they didn't the believe God was capable of protecting them so every single one of them died not making it to the promised land.
Miracles can deceive as well; a group of Christians called Pentecostals allegedly performed miracles causing many to be deceived. Scientists are able to perform many miracles by feeding the hungry and healing the sick so people put their faith in science rather than God. Even false prophets can perform miracles, Jesus said that the ones who cry out "Lord, Lord" will be casting out demons and performing great signs.
We cry out "Lord, Lord" yet we do not follow the teachings of Jesus, we don't trust that God will protect us, we trust society and the military and police to protect us and for that we will all die and never make it to the new promised land.
