Mirrors are fascinating objects. With a piece of glass and liquid silver, two ordinary things become an extraordinary object that reveals and reflects.
Painfully, it can reveal not only our physical faults, but it can also reveal many of our hidden faults. Faults that we feel disqualify us, or separate us from the grace of Christ. Yet, Paul is very clear in 2 Corinthians 12:9 that Christ's strength and glory are revealed in our weaknesses. I take that to mean if I can do it on my own, it doesn't tend to bring God glory. But if I live for Christ with my faults and let him make corrections were needed, he gets the glory!
Dramatically, when we are living in righteousness with God we can reflect the love and mercy and grace of Christ for others to see. Yeah, they will point out our weaknesses, yet the power of God will be undeniable.
Take a look into the mirror!
