The 20th century Norwegian pastor [Ole] Hallesby likens prayer to mining as he knew it in Norway. Demolition to create mine shafts took two basic kinds of actions. There are long periods of time, he writes, "when the deep holes are being bored with great effort into the hard rock." To bore the holes deeply enough into the most strategic spots for removing the main body of rock was work that took patience, steadiness, and a great deal of skill. Once the holes were finished, however, the "shot" was inserted and connected to a fuse. "To light the fuse and fire the shot is not only easy but also very interesting … . One sees 'results.' … Shots resound, and pieces fly in every direction." He concludes that while the more painstaking work takes both skill and patient strength of character, "anyone can light a fuse."

Pastor Tim Keller comments:

This helpful illustration warns us against doing only "fuse-lighting" prayers, the kind that we soon drop if we do not get immediate results. If we believe both in the power of prayer and in the wisdom of God, we will have a patient prayer life of "hole-boring." Mature believers know that handling the tedium is part of what makes for effective prayers. We must avoid extremes—of either not asking God for things or of thinking we can bend God's will to ours. We must combine tenacious importunity, a "striving with God," with deep acceptance of God's wise will, whatever it is.
