You’re missing something that is obvious to everyone around you. That’s spiritual blindness. You and I can function in life, and because we can, we don’t notice our blindness to our true condition. We go through life ignorant of the depths and extent of our sin. We cannot see it. Sin is blinding. By nature it fools us, and when we’ve sinned for a long time in the same way, we become less and less able to see it in all its ugliness. 

Every pastor, every biblical counselor has talked to a counselee that really couldn’t see his sin very accurately. You’ve patiently showed him how he’s hurting his marriage, how he’s not fulfilling his biblical role, how he’s not loving his wife as Christ loves the church, and he’s not seen it. He refuses your counsel. He doesn’t own his sin. He rejects blame. It’s difficult to communicate the biblical concept of spiritual blindness—that we don’t see our sin very clearly. Sin deceives us to its existence (Heb 3:12-13), and we want to be deceived about it.

In this life we will never have 20/20 vision about our own sin. The Laodicean church shows us that.

Revelation 3:17 (ESV) For you say, I am rich, I have prospered, and I need nothing, not realizing that you are wretched, pitiable, poor, blind, and naked.

Did the Laodicean church think that everything was okay while in fact, everything was radically wrong? Did they really believe that things were A-Ok when they were really wretched, pitiable, poor, blind, and naked? Yes they did. So do you. And so do I (Cf. Mt 7:3-5).

So what illustration can a biblical counselor use to communicate our tendency to be spiritually blind? Most use physical blindness which works, but has limitations. One, a physically blind person knows they are physically blind; a spiritually blind person often does not know they are spiritually blind. Two, physical blindness as an illustration is all or nothing, but there can be degrees of spiritual blindness.

Protanopia or deuteranopia are types of color blindness. With protanopia you cannot see the color red (1% of men) and with deuteranopia you cannot see the color green (5% of men). Most commonly a colorblind person struggles to differentiate between reds and greens. What is life like for the colorblind?
