[Gary Petty] Lawyer Abraham Lincoln was in a debate. He looked at his opponent and said, "If you had a cow with four legs and you called the tail a leg, how many legs would the cow have?" His opponent said, "Well, five." He said, "No, he wouldn't. He would still have four. Calling a tail a leg doesn't make it a leg."

You see truth doesn't depend on us having clever arguments or changing the meaning of words or even arguing more passionately. Truth is truth. The problem you and I have is that we tend to form our opinions around our emotions. So we look at everything through this emotional viewpoint.

Now we can argue passionately, but you know all opinions can't be the same and they can't all be right.

How do you determine what moral truth is? As Christians how do we determine that?

You know two men standing on a 1,000 foot cliff arguing over the law of gravity—they can argue. They can come up with clever arguments. They can be very passionate about it, but when they jump off it's no longer a subjective argument. As they plummet to the ground it becomes very objective and very hard hitting when they hit the bottom.

Objective truth comes from our almighty God who created the universe. He knows what is right and wrong. He knows what works. If you want to discover objective moral truth, the place to start is in the gospel in your Bible.

Read the gospels. Read the Ten Commandments, and read the book of Proverbs.

Here's what Proverbs says, "He who trust in his own heart is a fool, but whoever walks wisely will be delivered."
