Matthew 3:1-12; Mark 1:2-8; Luke 3:3-18 You remember that the old priest named Zechariah had a son named John. (See picture 6.) This boy also grew up and became a great prophet. He lived in the desert. Many people went there to hear him teach. He told them that God would send someone to save them. He also warned them that they must turn from their evil ways. Those who believed John's message were baptized in the river. Baptism showed that they wanted to turn away from evil and to follow God's ways.
