But be doers of the word, and not hearers only, deceiving yourselves. For if anyone is a hearer of the word and not a doer, he is like a man who looks intently at his natural face in a mirror. For he looks at himself and goes away and at once forgets what he was like. But the one who looks into the perfect law, the law of liberty, and perseveres, being no hearer who forgets but a doer who acts, he will be blessed in his doing.
How often do you look into the mirror, walk away, and forgot what you look like? Seems foolish, doesn't it?
Now, how often do you read scripture and meditate on the Gospel, and then still try and work for your salvation? Or consider yourself more righteous on certain days that the LORD has granted you victory in some sins?
Every single day, I am that idiot who looks into the mirror of the Law, walks away, and forgets the grace and mercy of my salvation in Christ. I start to act prideful, doubtful, self-sufficient, faithless, foolish...I constantly need reminding of who I am in Christ.
Thankfully, the LORD has provided many brothers and sisters in Christ who have reminded me what I really look like. And I must say, it is humbling!
