Hello @olufunke
You actually did something great reading @surpassinggoogle life changing and thought provoking article to your brother and to be sincere this is my first time hearing of "glaucoma" (I might have been living a cave) and here i am with inspiration for him.
Please help me read out to him
Life purpose can not be defeated when determination is in place even glaucoma can't. Potential can still be unleashed even in the worst condition of life. Every bad condition has an expiring date.
He can and will be free from that condition. Let him know that there is nothing impossible to a man that believe even the most impossible things of life are doable.
Lastly, coming back to @surppasinggoogle idea; we are not our conditions and conditions are instrument for transformation. Miracles happens when faith is demonstrated.
He will see again in Jesus Name.
Wow.... This touched me. I just read it to him again. In his words, "your words are comforting and has boosted my faith to know that if people can believe in my restoration (sight), I don't have an excuse not believing in God to do it in me, thank you so much". We are grateful
