One night as we were packing up after a concert, we sent a young woman to pick up our children from the home they were staying in. Since the children didn't know her, I told her to give our son, Trevor, our secret family code word so he would know she was authorized to pick them up.

A little later I received a phone call. Trevor refused to leave because the woman hadn't given the right word. The mix-up was on my part--I had said the code word was "Dinosaur Monster," which my son informed me was incorrect. "It's Dinosaur!" he said.

"Are you sure? I was certain it was Dinosaur Monster," I replied.

"I'm sure," said Trevor confidently.

"Well, OK, son," I carried on. "You're probably right. But it's OK for you to come back to the church with this lady."

There was silence on the other end of the line. Then Trevor said, "Who is this?"

"It's me, your father, Mickey Moore! Now get in the car and come on!"

"All right," he replied and hung up.

It was an odd feeling to be interrogated by my six-year-old son. He knew the word, and even though he was given words that were very close to the real thing, they weren't true--and he knew the difference.

A mature Christian knows the Word of God and is not easily tossed about "with every wind of doctrine" (Ephesians 4:14). We are to test the spirits by the Word to see if they are true.
