The stats over the years say that 95% of blind&visually impaired people do not attend church services and are not active in a local congregation. That means that many blind/visually impaired do not hear the saving Gospel in the company of others. Sure, they are free to explore the plethera of expressions given to American spirituality on the TV. This means, though, their trus in God is clouded.
How counter to the stalwart clarity the purely taught Gospel of Jesus Christ proclaims. (1 Cor. 2:5, Eph. 2:8-9, John 3:16) Those who, by virtue of their fears or ignorance of the transportation resources available to them, forsaking the company of fellow believers (Heb. 10:25), are not being freed through faith in Christ to rejoice in this clarity.
Put that against the bare, cold, uncompromising fact of which the apostle John writes in His first epistle, that whoever does not have the Son does not have life. (1 John 5:11-12)
The statistics should not do either of two things: 1. They should not reduce to mere statistics placarded on a bulletin's front cover. They tell the rea story of real people. Many who otherwise would hear the Gospel are bombarded with hours of confusion that is really no Gospel at all. (Gal. 1:8) 2. The statistic should not impel us only out of guilt to run headlong into doing mission work. Rather, the sheer desire to speak aloud the faith Christ Jesus has called us to confess puts us in places where the Word gets out to other people. God creates faith by means of His Word. He nurtures that faith through His Word read, spoken, cleansing, distributed.
Now, is the population of heaven and hell static? Yes. God knows for all time who will believe and who will not. We, in our finitude do do not know this number. Rather, our Lord has given us His blessed command and promise: "Go, there, make disciples of all nations" by means of "baptizing them and teaching everything I have commanded you. And surely I am with you till the end of the age." (Matt. 28:19-20)
God, our One and Only Savior from sin, death, and the power of the devil calls us to proclaim His Gospel to those who do not know or trust it.
