15 Now the Lord said to [f]Joshua, 16 “Command the priests who carry the ark of the testimony that they come up from the Jordan.” 17 So Joshua commanded the priests, saying, “Come up from the Jordan.” 18 It came about when the priests who carried the ark of the covenant of the Lord had come up from the middle of the Jordan, and the soles of the priests’ feet were [g]lifted up to the dry ground, that the waters of the Jordan returned to their place, and went over all its banks as before.
19 Now the people came up from the Jordan on the tenth of the first month and camped at Gilgal on the eastern edge of Jericho. 20 [h]Those twelve stones which they had taken from the Jordan, Joshua set up at Gilgal. 21 He said to the sons of [i]Israel, “When your children ask their fathers in time to come, saying, ‘What are these stones?’ 22 then you shall inform your children, saying, ‘Israel crossed this Jordan on dry ground.’ 23 For the Lord your God dried up the waters of the Jordan before you until you had crossed, just as the Lord your God had done to the [j]Red Sea, which He dried up before us until we had crossed; 24 that all the peoples of the earth may know that the hand of the Lord is mighty, so that you may [k]fear the Lord your God [l]forever.”
Not only is it good for us to have reminders, but it’s good to have things that will stand out so that your children ask about them. Or things that your friends will notice and say, “what’s that all about?”
Then you can say, “it’s a reminder that the Lord is mighty…” and share the good news, beyond anything the Israelites knew in that day. The fact that God is mighty AND that he loves us enough to take the penalty for our sins and give us eternal life with Him.
We all need reminders, but it’s even better when our reminder is also a conversation starter about God.
