Christians will assert that the “God of the gaps” epistemology doesn’t adequately describe their knowledge about God and his activity, since God is not just known in the gaps of our knowledge. But consider how science has filled in the gaps when it comes to prayer and healing.
When ancient people prayed for their “daily bread,” they did so because crops could sometimes fail in their local area, or a hunter may fail to bag a deer. Such disasters as these things could produce hunger, and possible starvation. Do Christians today have the same fervor when they pray for their “daily bread” as ancient Christians did? Many Christians in the industrialized West don't even pray before every meal, especially when they eat at a McDonald's. Many if not most all of the Christians in the industrialized West, take their food pretty much for granted.
When Christians are very sick, they will take a prescribed pill from the doctor and be confident they'll get better, even if they do pray. But in the ancient times when someone got very sick they could die. Christians in the ancient past had no choice but to depend almost completely upon God's help here. Are Christians saying they wrestle with God over sickness in prayer like the Christian people of old did? Or is their confidence more in the results of science and medicine, than in God? I know the answer. They just haven't admitted it yet.
As science helps Christians with their daily meals and with healing, they believe in prayer and in God’s help less and less, and they believe in science more and more. Say it isn’t so!
