“And Moses with the elders of Israel commanded the people, saying, Keep all the commandments which I command you this day. And it shall be on the day when ye shall pass over Jordan unto the land which the LORD thy God giveth thee, that thou shalt set thee up great stones, and plaister them with plaister: and thou shalt write upon them all the words of this law, when thou art passed over, that thou mayest go in unto the land which the LORD thy God giveth thee, a land that floweth with milk and honey; as the LORD God of thy fathers hath promised thee.” Deuteronomy 27:1-3 (KJV)
These are stones which the children of Israel are being commanded to place on the other side of Jordan, after they have crossed over into the promised land. They may be the stones which John the Baptist addresses in Matthew 3:9.
They were to remind the people that they were a people of the word of God, and it was to have a firm place in their hearts and lives. It was not to be just in their mouth, but come from their hearts, and lived, shown in their lives. Ditto for the Christian today.
It could also be the stones of which Jesus referred when we read,
“And they brought him to Jesus: and they cast their garments upon the colt, and they set Jesus thereon. And as He went, they spread their clothes in the way. And when He was come nigh, even now at the descent of the mount of Olives, the whole multitude of the disciples began to rejoice and praise God with a loud voice for all the mighty works that they had seen; saying, Blessed be the King that cometh in the name of the Lord: peace in heaven, and glory in the highest. And some of the Pharisees from among the multitude said unto him, Master, rebuke Thy disciples. And He answered and said unto them, I tell you that, if these should hold their peace, the stones would immediately cry out.” Luke 19:35-40
The word of God is the source of our spiritual food. Even we do not eat it we grow weak, sickly, and poor. Will you make the Word of God your most important meal today? Will you hear God; or will the stones cry out? Creation still declares the glory of God (Psalm 19:1).
