Ask a physically blind person if they’re blind and they’ll say, “Well, yeah, of course.” Ask a spiritually blind person if they’re blind, and they’ll say, “What? Who do you think you are accusing me of being blind?! You’re the blind one, you fool!”
When people are physically blind, they’re aware of it, and they address it. The spiritually blind aren’t aware that they’re blind; therefore, they don’t address it.
Jesus once said, “For judgment I have come into this world, so that the blind will see and those who see will become blind” (John 9:39).
Jesus has the right and will exercise that right to judge all people. He won’t judge you on whether you’re blind or not but whether you are aware of it. Whether you see your blindness and seek help and repent.
To make that possible, Jesus himself became blind. The night before he was crucified, the guards “began to spit at him; they blindfolded him, struck him with their fists, and said, ‘Prophesy! Who hit you?’ And [they] took him and beat him” (Mark 14:65; Luke 22:64).
Jesus was blinded. He couldn’t see the sinners smashing his face. Not because of the blindfold (Jesus can see through anything) but because he closed his eyes and became the curse for spiritual blindness.
So you’re not spiritually blind when you see Jesus as your Savior. Your eyes are opened to see his mercy and to see others who need your mercy too.
