Why are we not seeing miracles in our lives?

Caleb's answer is useful.

As an interesting data point, I have a friend, now dead, who was a translator with SIL (Wycliffe) in a Papua New Guinea Villages, very close to the PNG-Irian Jaya border. This area was much more remote than many and so less influenced by western contact. She said that initially miracles of a biblical nature were relatively common amongst thje Christian community, but that it seemed that they decreased as westernisation and familiarity with external contact increased over many years. Obviously with a sample of one area and one person's observations it is not certain how (inversely) causally related the miracles and degree of westernisation were, but worth noting.

As one who is older than young I have noted over many decades that mountains seem to move when viewed from the corner of the eye and are much less likely to do so when stared at. I also find that that which was absolutely certainly miraculous at the time, is much more questionable at a later date, and increasingly so as time progresses. I am not suggesting that the details are less convincing but that as the effect on attitude and behaviour fade and memories of how real an event was that we tend to let the louder less still voices of cynicism and disbelief increasingly attack the memories.

I have personally experienced a few events that seemed to incontrovertibly be miracles by any statistical evaluation - and a few survive as miracles even with long term memory, but even those would have been questioned and / or rejected at the time by those who feel bound to necessarily reject all such events.

I'm an engineer. I tend to informally and even formally assess apparent probabilities of events when they stick well enough out of the noise to be notable. Some few do this really well. I have experienced a number of events which matched specific requests with probabilities I'd rate in the millions to one. And other events of similar probability which were not absolutely identifiable as specific answers but which "worked together for good" at equally large probability ratios.

While minor by most standards the following was interesting to me:

I've never liked "healing" stories which implied a degree of flippancy on God's part (legs being lengthened too much with prayer and needing more prayer to get it right) but even they may have their place.

I personally experienced instantaneous healing of a 'smallish' but significant injury which in normal events would only have been painful and inhibiting while it healed but which was about to cause major problems. I was about to lead a church group on a hiking trip in steep and rugged company with a painful leg injury acquired a few days before through acting extremely stupidly on a motorcycle. My 'fervent' prayer was very specific about why I needed healing and what events had to be covered. Nothing happened and I approached a several day event without healing - I guessed that God's answer at that stage was "No!". At the exact moment of commencement I received essentially complete healing. This lasted for about 3 days and at the exact moment that the "event" ended the healing instantaneously reverted and I then had to heal again in the normal manner. I received exactly what I asked for in order to allow me to meet other people's needs. Interesting.

On the contrary, I would suggest that miracles do happen fairly often. There are many testimonies of doctors beginning a massive surgery to remove cancer only to find that the cancer mysteriously disappeared overnight.

Additionally, a significant percentage of Muslims who become Christians do so because of a vision or dream where Jesus Himself appears to them. This certainly could be considered miraculous, as many of them risk their lives to turn to Christianity, which they hated for their entire lives.

Now, the Bible seems to indicate that God responds according to our faith, so the lack of miracles or answered prayer can be an indicator of a lack of faith in a community.
