In the New Testament, Jesus does lots of impressive miracles.
More precisely, they were impressive for the time. Today we surpass them with technology so regularly that we often don’t notice. Let’s compare the miracles of Jesus with what modern technology can do.
Jesus walked on the water. We can’t walk on the water, but we can travel on the water in a vast array of boats, both large and small, powered and wind driven. For example, an aircraft carrier can carry 5000 people, sail at 30+ knots, and operate for 20 years without refueling. We can travel under the water with submarines. We can fly above the water with airplanes. We have even gone to the moon.
Feeding of the 5000. We can’t feed people with magic, but we can still feed lots of people. Norman Borlaug has saved perhaps one billion lives because of improved strains of wheat, for which he won the Nobel Peace Prize. The Haber process, which turns nitrogen into ammonia, produces fertilizer that is estimated “to be responsible for sustaining one-third of the Earth’s population.”
Cursing the fig tree. Jesus was hungry, but it wasn’t the season for figs. Nevertheless, Jesus cursed a fig tree, and it withered. While we can’t destroy trees with magic, we’ve got the destruction thing figured out. We have herbicide that kills plants. We have chain saws and bulldozers. We have dynamite and hydrogen bombs.
Miraculous catch of fish. We can’t catch fish with magic, but modern fishing trawlers do a good job at catching lots of fish. They do perhaps too good a job, and aquaculture now produces as much tonnage as wild capture to reduce humanity’s footprint.
Calming the storm. We can’t stop storms, but we have gotten pretty good at prediction. We’re able to minimize the loss of life from disasters like the 1900 Galveston hurricane. Technology can warn of tornadoes and tsunamis.
Prophecies. Jesus predicted his death and his second coming, but pause for a moment to consider this quote from Shakespeare:

Glendower: I can call spirits from the vasty deep.
Hotspur: Why, so can I, or so can any man;
But will they come when you do call for them?

Jesus made prophecies, and so can any man, but do they actually come true? His predictions of a second coming within the lifetimes of some witnesses didn’t come to pass. His prediction of his death is part of a story that we have little reason to see as history.
Healing miracles. Jesus did many of these (I recently explored the healing miracles here). For example, he healed lepers. We don’t heal lepers with magic but with antibiotics. Leprosy is no longer much of a problem, as is the case for smallpox, bubonic plague, and polio.
Jesus cast out demons. We don’t, because we know they don’t cause disease. We can’t cure all illnesses, but we do a better job now that we’re focused on the actual causes.
Jesus restored sight and hearing. Here again, we can’t prevent all such cases or cure all that occur, but medicine has made remarkable improvements in health.
Jesus raised the dead. We don’t use magic, but modern medicine has returned thousands from conditions that just a century ago would be considered “dead.”
What Jesus didn’t do. Jesus didn’t do any miracles against which we can parallel clean water and sanitation. Or civil engineering—roads, bridges, and buildings. Or communication—telephones and the internet. Or the energy industry or the chemical industry or the transportation industry.
What Jesus did was basically just party stunts. From helping God create the universe, he was reduced to doing magic for small audiences and today just appears in toast.
Some Christians will agree and say that Jesus didn’t come to improve the lot of people on earth but simply to spread his message.

Do not believe me unless I do the works of my Father. But if I do them, even though you do not believe me, believe the works, that you may know and understand that the Father is in me, and I in the Father. (John 10:37–8)

Okay, we can’t duplicate what Jesus did by magic. But everything that has been improved for humanity has been improved by humanity. Technology puts the claimed miracles of Jesus in perspective.

Religion may not be dying just yet,
but it’s sure getting feeble in this age of reason.
