You will know yourself better
Many metaphors are employed in the pages of scripture to describe itself (e.g. a sword, Hebrews 4:12; A seed, Luke 8:11; Light, Psalm 119:105 etc), but this one from James is particularly interesting. He explains that the word of God (i.e. the scriptures) is a bit like a mirror.
Mirrors are useful because they show us what we look like, and once we can see what we look like we are able to identify if and where any adjustments need to be made to our hair, face, clothing etc in order to be presentable. It would be difficult to live in a world without any mirrors.
The word of God works in a similar way, James explains, except that the mirror of the word is not so concerned to show us how we look on the surface, but rather to show us what we are like on the inside. The scriptures are a mirror into our hearts. A shiny piece of glass can show us what we look like; the scriptures show us who we are. Sometimes the mirror on the wall will make you feel good (when you’re having a good hair day), sometimes it will be less encouraging (the morning after a rough night!), but one thing you can always be sure of: it will never lie to you. The same is true of the scriptures. Sometimes it will show you things about yourself that deeply humble you, (e.g. Romans 3:10-12). Other times it will show you things that will make your heart soar (e.g. Zephaniah 3:17). But, like the mirror on your wall, it will never lie. So let’s quit imagining that the bible is outdated and irrelevant, and let’s instead treasure it as a faithful friend that can always be relied upon to show us who we really are and what we really need.
