People with severe ailments and physical abnormalities or things missing also are either Christians or not. There is the blind, that am****ted limbs and all other diseases ( I have one myself that is incurable or as of now has no earthly cure, it's called Crohn's disease). Those with those problems often blame God, get angry and are hateful toward God and everything else. Others say their ailment is a blessing because it caused them to look, and find, for more than just what's on this earth. I'm not bitter at God for my disease and just because there is no known cause or cure doesn't make me blame God for it. It happened. As a person with a potential life threatening disease, as people have died from it and do each day, I look at it as a physical earthly abnormality. It also helps me realize that there are earthly things and heavenly things. I know that my problems are physical ones and that there is something on the other side of the physical. I know that my eternity is not a physical one or not at least with this particular physical body. My eternity is a spiritual one. Whether my spirit will again find a physical body I do not know. I feel I will one day inherit a glorified body for that is what scriptures say.
Look at Helen Keller and all her deficiencies yet through it all she found and believed in God and did not blame God but praised him. How did God work through her? God often can work through abnormalities and problems people have to show that there is more than just what's here and now. I truly believe God can do anything. Salvation, healing, answer to prayers, or the Holy Spirit all do not conform to the laws of nature. Just because a person does not get the particular answer from God doesn't mean God fails. Helen Keller could have blamed God but didn't. She continued to grow closer to God and saw. She saw and had spiritual sight with spiritual eyes and she was able to see something that many with eyes never see. She saw the Grace of God, and I fully believe she saw and knew the Gift of God. She also saw that what was on this earth is not the end and not the most important thing in life. She actually saw much more than many with eyes will ever see.
