One of the first things they teach in driver education is that when you check the rear view and side mirrors, you still have to glance over your shoulder to check the blind spots the mirrors don’t cover. During my many years of driving I was often shocked to find a vehicle in that blind spot that caught me completely by surprise and that prevented some very serious accidents. I can’t drive anymore due to glaucoma damage to my right eye, which has a sizable blind spot as a result. Thankfully eye drops are keeping the glaucoma under control to prevent further damage to that eye or any damage to my good left eye. Even when I walk, I have to turn my head a little to survey the floor or sidewalk for tripping hazards I might otherwise miss.
Spiritual blind spots are much harder for us to check. We examine ourselves carefully but we often cannot see a sin of omission or a character trait that seems harmless to us that could put us on the proverbial slippery slope to disaster. When I was a kid, sometimes a classmate would pull a prank by slapping you on the back and tape a sign to your back that read “IDIOT” or “KICK ME”. I think the enemy does that sometimes placing a sign others can see, but it is oblivious to us and even a mirror doesn’t help. One of the reasons we need to surround ourselves with Christian family and friends is that they will have our back, hold us accountable and help us remove the sign. Of course, we also have the Holy Spirit dwelling within us. We can ask Him to do a security check much like David asks for in Psalms 139:23.
God of Creation who can see past, present and future as a continuum and can see every thought in our mind and desire of our heart surely has no blind spots, right? Buzzzz! Wrong answer! God designed his own blind spots for our benefit when He sent Jesus to die in our place. God can’t stand sin. When we accept Jesus as our Savior, His shed blood cleanses us of our sins so we can stand righteous in God’s sight. He no longer sees our sinful nature, but the righteousness of His Son. (Romans 5:1 & 5:9)
