"Jesus said, 'For judgment I came into this world, that those who do not see may see." ( John 9:39 ) And "I have come as light into the world, that whoever believes in me might not remain in darkness." ( John 12:46 )
Jesus did not merely come to pay the ransom and to call the sinners to repent, He was also born to help lead the people to witness the True Light and walk in the True Way. Our problem was not only our need to be set free from Satan’s slavery, nor to finally find the True call. A main problem was also our moral blindness; we were in need to that gift of insight. We were not ‘literally’ blind; but, simply, we were blind to some of the crucial beliefs that enable us to see and embrace.
This is why Christ came: That those who do not see may see.
