And he answered and said unto them, I tell you that, if these should hold their peace, the stones would immediately cry out. Luke 19:40
Rocks, stones, pebbles, are you forever finding them in your children's pockets, in the bottom of book bags, or in the corner of their sock drawers? Maybe there's even one in your pocket once in awhile. The Bible has a lot to say about rocks. Though the word rock or stone isn't used, one of the first places in the Bible to allude to rocks is Genesis 8:20 when Noah came off the ark and built an altar to offer sacrifices. Abraham built altars everywhere he traveled.
Rocks weren't just used for altars. Jacob used a stone for a pillow while camping out. The next day he stood it up as a pillar to help him remember God's promises. Joshua was commanded to place 12 stones in the Jordan River where the priest bore the ark of the covenant. He was to take 12 stones out and place them for stones of remembrance of what God did for them.
David said God was the Rock of his salvation (Psalms 89:26).
Paul in I Corinthians 10:4 says "that Rock was Christ". Rocks are common everyday things, but if we put on our spiritual eyes the stones will cry out to us of Jesus every day.
What can you do with a rock?
Skip it across the water or plunge it in the deep part and see how many circles it will make. If we take the message of Jesus with us we can reach an ever widening circle of people.
Paint it and leave it for someone to find. Maybe paint a pretty picture and add a Bible verse as a witness.
