“On the cross and in the resurrection, Christ broke the power of sin over us (Rom. 6:1-14), but the presence of sin remains. Sin is being eradicated within us, and this process will continue until we are sin-free. But while sin remains, we must remember that sin is deceitful.
Sin blinds– and guess who gets blinded first? Me! I have no trouble seeing the sins of my family, but I can be astonished when mine are pointed out! Since each of us still has sin remaining in us, we will have pockets of spiritual blindness. Our most important vision system is not our physical eyes.
We can be physically blind and live quite well. But when we are spiritually blind, we cannot live as God intended… Physically blind people are always aware of their deficit and spend much of their lives learning to live with its limitations.
But the Bible says that we can be spiritually blind and yet think that we see quite well. We even get offended when people act as if they see us better than we see ourselves! The reality of spiritual blindness has important implications for the Christian community.
The Hebrews passage [Heb. 3:13] clearly teaches that personal insight is the product of community. I need you in order to really see and know myself. Otherwise, I will listen to my own arguments, believe my own lies, and buy into my own delusions.
My self-perception is as accurate as a carnival mirror. If I am going to see myself clearly, I need you to hold the mirror of God’s Word in front of me.”
