Four forces act on airplanes as they fly high in the sky:
Lift up (from the wings) opposes Gravity down. Thrust forward (from jet engines or propellers) opposes Drag back (resistance from the air). When a plan is at cruise level, all four are in equilibrium (balance).
HOW THEY WORK TOGETHER
When we increase drag, we descend. If we reduce thrust, we descend. If we increase weight, we descend.
When we reduce weight, we climb, and when we increase thrust, we climb.
Equilibrium is fine for an airplane that is cruising along, but Christians don’t want to just cruise, they want to rise. Paul wrote: “So we have many people of faith around us. Their lives tell us what faith means. So let us run the race that is before us and never give up. We should remove from our lives anything that would get in the way. And we should remove the sin that so easily catches us” (Heb. 12:1, ICB).*
AN AIRPLANE’S JOB
An airplane carries people from point A to point B as fast and efficiently as possible. To do this, we have to reduce the impediments (things that slow us down) that we run into.
The main impediment to flight is air molecules. A lot of air molecules exist at sea level, but there are much fewer at 43,000 feet, the maximum altitude a plane can safely fly. Since planes hit fewer molecules at high altitude, they go faster there.
THE CHRISTIAN’S JOB
We have a job to do too, and it is best done at the altitude God designed us to operate.
The Bible tells us: “And I, the Lord, will carry you to the high places above the earth.” (Isaiah 58:14, ICB).
English is the international language of flight. All flight controllers and commercial pilots who fly international flights are required to speak English.
Pilots and copilots on major airlines are not allowed to eat the same food to avoid the possibility of food poison sickening the entire flight crew.
The atmosphere in an airplane cabin dries out a person’s nose, and changing air pressure numbs about a third of a person’s taste buds. That’s one reason airlines add lots of spices and salt to their foods.
