Knowing how to change the tire on a car is a very important “human” trait. Imagine one of our brother’s or sister’s in Christ on the side of the road, needing help with a flat tire. I recall three times in college helping women change the tires on their car so that they could get to home or work on time. What a great way to meet your future spouse or for someone to experience the generosity of the body of Christ.
Bring a car mechanic in to show it in great detail. Have the youth in your group actually go through their cars and make sure they have everything they need to change a tire.
