God uses the language and experience of disability to help us understand how we are spiritually: blind, deaf, and dead. We need a radical, life-giving Savior who pursues us – and God gave us Jesus!
When addressing the unsaved, preachers often draw an analogy between God’s sending of the Gospel to the sinner, and a sick man in bed with some healing medicine on a table by his side: all he needs to do is reach forth his hand and take it.
But in order for this illustration to be in any wise true to the picture which Scripture gives us of the fallen and depraved sinner, the sick man in bed must be described as one who is blind (Eph. 4:18) so that he cannot see the medicine, his hand paralysed (Rom. 5:6) so that he is unable to reach forth for it, and his heart not only devoid of all confidence in the medicine but filled with hatred against the physician himself (John 15:18).
O what superficial views of man’s desperate plight are now entertained! Christ came here not to help those who were willing to help themselves, but to do for His people what they were incapable of doing for themselves: “To open the blind eyes, to bring out the prisoners from the prison, and them that sit in darkness out of the prison house” (Isa. 42:7).
