"Men more frequently require to be reminded than informed."Samuel Johnson, prolific writer and lecturer, wrote that over 300 years ago. It's still true.
You see the same idea throughout the Bible as well. In the Old Testament, the feasts and festivals came about to remind the people of pivotal events in their history. Patriarchs built altars so that others would ask and the tales repeated.
Why? People forget.
Moses, in his final speech to the people of Israel before they entered the Promised Land, reminded them to care for those who couldn't care for themselves. Why? "The Lord your God redeemed you."
Although the Israelites had been slaves in Egypt, unable to care for themselves, God had set them free. God wanted them to give as they had been given. They had been given a free gift but they tended to forget.
And we do, too.
Peter wrote that "I will always remind you of these things, even though you know them and are firmly established in the truth you now have." (2 Peter 1:12)
What we know, we still forget. We need remembrances. And they can be found in the simplest places: church services, fellowship with believers, Bible studies, conferences, retreats. I knew a woman once who cut her hair to celebrate God's hand in her life. Another planted a tree.
All to remember. What will you do today to remember?
