This is an object lesson that we have used to begin Confirmation classes but is fine any time. Have a big bag of the larger-sized balloons. Line up your group at one end of a large room or sanctuary. Tell them that they are each trying to “fly” their balloons from the startring line past the designated finish line. Of course they fill the balloons full of air and let go–but the balloons almost never go in a straight line! They can fly at right angles or behind you. Use this to illustrate the “Spirit blowing where it will” and that on life’s journeys, we may not be going where we want all the time, but God might have a different destination in mind or a different path to our future.
