We tend to forget even the most important things. No matter how necessary an idea is to our spiritual health, it tends to slip away from us over time if it is not periodically refreshed.
So we need things that jog our memories: physical, visible objects that, when we see them, bring back to our minds the things that have started to slip away.
In Num. 15:38,39, God told Moses, “Speak to the people of Israel, and tell them to make tassels on the corners of their garments throughout their generations, and to put a cord of blue on the tassel of each corner. And it shall be a tassel for you to look at and remember all the commandments of the Lord, to do them, not to follow after your own heart and your own eyes, which you are inclined to whore after.”
I have found it helpful to surround myself with physical objects that serve a similar function in my life. For example, I often carry in my pocket a small, smooth stone that is engraved with the word “Valor.” Every time I feel it in my pocket or take it out and look at it, I am reminded to have the courage to do what my conscience tells me is right. And in my home there are many other objects that I have assigned symbolic meanings to.
I recommend this practice to you. The objects you select can be almost anything, and the meaning can be anything you assign to them. But the more of these you have around you every day, the more you will be reminded of the things that these objects symbolize to you.
Such “reminder objects” will refresh ideas that will get away if they’re not brought back to mind once in a while.
