Read John 9:1-3
The disabilities that one has is not the result of sins, but that the works of god may be revealed in you.
As you go through the difficulties in life, know that you are not alone, but that his rod and his staff can comfort you (psalms23). May god strengthen your faith, so that you may lean on him to carry you. By so living, may his works be revealed in you and may others be helped by you.
