Objects: Bathroom scale, measuring cup, ruler, tape measure, watch or clock, a quart jar, dictionary, a teaspoon & tablespoon, a chalk line, a plumb line, a level, etc.
Set up: Your object lesson can be set up in a variety of different ways. One way would be to gather as many common "standards" as you can get and bring them with you, lay them out where all can see them and start your illustration of standards from there, or you might display a grouping of common and not so common standards, including the Bible and throw in a big red apple too. Ask the group which one of these items is not a standard. Other good questions to ask would be . . . (1) Why are standards necessary? (2) How are they established? (3) Who makes the standard? (4) Which one of this group is the most rarely used standard? (5) Are there different standards in different countries? (Metric standard) (6) Will standards allow you to cheat? (As an example, how can one cheat in using a scale?) (7) Are standards made to keep people from cheating? (8) In which way does the Bible become a standard? (9) Is the Bible only our standard or the standard for others? (10) Can you cheat in using God's standard, the Bible? (11) If so, how?
Illustration: The markets in third world countries are very colorful and full of noisy and animated people. A place where there is always a lot of arguing and haggling over price. Part of the reason for the haggling is that often there are no set standards. No scale to weigh things on. With no standards everybody insists they are right and who can argue with that?
Our lives are full of a variety of standards. We use them every day. From the scale in the bathroom or the measuring cup in the kitchen to the ruler you take to school. These are common standards we use to measure. A mile a quart a ton or a gallon, each is a common term of measure. We regulate our life with these standards, we communicate using these common standards. We don't argue or hassle on these points. Why? Because we agree on a standard.
Lesson: As Christians the Holy Bible becomes our common standard for many things in our inner lives. Our values, and behavior like ethics and morality, our purpose here on earth and of course our very picture of God. The Bible becomes our standard of what's acceptable or not acceptable and what's right and what's wrong. Good question, What would Christianity be like if we had no common standard? Another good question, if the Bible is our common standard why are there so many denominations and cults in Christianity? Regardless the Bible has taken it's place as one of the worlds leading moral standards.
Application: Those who are wise make it a point to learn, use and respect this standard and apply it to their lives.
