God still answers prayers

I've got a friend who has a son just a few months older than my son. He has vision problems. About a year ago, his vision tested at -8. He's been wearing glasses and doing patch therapy for the past year. (His mom puts a patch over the good eye for a few hours a day). She asked for prayer for him Sunday night at church. She prefaced her request by saying that she was going through the Bible study Believing God and that last week, she felt God telling her that if she would bring her son up Sunday night then He would improve his vision. She did. She felt again that she needed to bring it up at Bible study last night. She did. We all prayed for her and her son last night. I got a call a little while ago from her sister-in-law that his vision went from the -8 of a year ago to 5.5 today. I'm not sure what the numbers mean, but I do know that going from negative to positive is an improvement. Praise God!
