The thing is, the miracles of the bible were witnessed by thousands and done publicly and had undeniable physical evidence. They were not done in controlled or remote circumstances in most cases. They had many witnesses. I think often we confuse God's providence with a miracle. A miracle, biblically defined, is something that defies nature and is undeniably God (i.e. seas parting, legitimately crippled persons instantaneously recovering, undeniably dead men coming to life, burning bushes that are not consumed, 3 people thrown in a fiery furnace and not being consumed, etc.). This is not what we see today, only hear about. In a digital age, i would expect a bonafide miracle to be massively published throughout the world with huge, credible sources as witnesses to it. This simply isn't the case.
Praying for healing and someone being healed over time (either naturally or through medical means) is not a miracle, but a work of God's own will and providence. I am not opposed to miracles by no means, but we tend to label things that are not miracles as miracles, when in reality it is just an act of providence. More specifically, I believe the sign-gifts have ceased according to evidence in Paul's statement in 1 Corinthians 13, early church consensus, biblical warnings of end-time deceptions and delusions, and lack of credible witnesses in modern times.
To say the sign gifts are still in full operation is to deny the sufficiency of scripture and leaves the canon open. This is a dangerous prospect as it is abused worldwide by the Benny Hinn's of the world, and in a very cruel fashion. The church is being overrun by a circus and this is the major cause why.
