In Phuket, Thailand, Tilly Smith, a determined 10-year-old girl, saved her parents and dozens of fellow vacationers from the deadly tsunami because she had studied a school geography lesson, and then courageously spoke what she knew to be true.

As Tilly's family enjoyed a day at Maikhao Beach, the sea began to bubble and rush away from the shore. While the adults were merely curious, Tilly was petrified with fear.

"Mummy, we must get off the beach now!" she said. "I think there's going to be a tsunami."

The adults didn't even understand her warning until Tilly referred to it as a tidal wave. Once they understood, they all believed the youngster and evacuated the area. Minutes later the water surged right over the beach and demolished everything in its path. The resort was destroyed, but that section of beach was one of the few places along the shores of Phuket where no one was killed or even seriously hurt.

Tilly was praised for raising the alarm.

"I think it's phenomenal that Tilly's parents and the others on the beach are alive because she studied hard at school," said the hotel's manager. "She's a hero."

Tilly gave the credit to her geography teacher for his lesson on how earthquakes cause tsunamis.

She explained, "I was on the beach, and the water started to go funny. I recognized what was happening and had a feeling there was going to be a tsunami."

As those who know that judgment is coming, but also know that God has provided a way to escape, are we ready, willing, and courageous enough to tell others?
