I truly believe that the pastor needs to take the lead on helping a church to become disability-friendly. This can happen in many ways, but one is to preach on disabilities. There are a number of passages that deal with disabilities that would make for a good sermon.
Here are some suggestions:
Now Jonathan, Saul’s son, had a son crippled in his feet He was five years old when the report of Saul and Jonathan came from Jezreel, and his nurse took him up and fled And it happened that in her hurry to flee, he fell and became lame And his name was Mephibosheth. – 2 Samuel 4:4
You shall not curse a deaf man, nor place a stumbling block before the blind, but you shall revere your God; I am the LORD. – Leviticus 19:14
‘Cursed is he who misleads a blind person on the road.’ And all the people shall say, ‘Amen.’ – Deuteronomy 27:18
“In that day,” declares the LORD, “I will assemble the lame And gather the outcasts, Even those whom I have afflicted. “I will make the lame a remnant And the outcasts a strong nation, And the LORD will reign over them in Mount Zion From now on and forever. – Micah 4:6-7
“Behold, I am going to deal at that time With all your oppressors, I will save the lame And gather the outcast, And I will turn their shame into praise and renown In all the earth. – Zephaniah 3:19
