What does the Bible say about memorials in Joshua?

In Joshua 4, the memorial of twelve stones taken from the Jordan River represents a reminder for the children of Israel concerning God’s miraculous provision in helping them cross into the Promised Land. When future generations ask about these stones, parents are instructed to explain that they signify the moment when the Lord dried up the Jordan River. This practice emphasizes the importance of remembering God's acts and teaches future generations about His faithfulness, instilling a sense of awe and reverence for the Lord's power and promises.
