With regard to physical disabilities, God admits to being responsible for them.
Exodus 4:11
Who maketh the dumb, or deaf, or the seeing, or the blind? have not I the LORD?
Not only that, he also bars them from Heaven:
Leviticus 21:17-23
"Whosoever ... hath any blemish, let him not approach to offer the bread of his God. For whatsoever man he be that hath a blemish, he shall not approach: a blind man, or a lame, or he that hath a flat nose, or any thing superfluous, Or a man that is brokenfooted, or brokenhanded, Or crookbackt, or a dwarf, or that hath a blemish in his eye, or be scurvy, or scabbed, or hath his stones broken; No man that hath a blemish of the seed of Aaron the priest shall come nigh to offer the offerings of the LORD made by fire: he hath a blemish; he shall not come nigh to offer the bread of his God. ... Only he shall not go in unto the vail, nor come nigh unto the altar, because he hath a blemish; that he profane not my sanctuaries."
Truly he is a loving God, who is verrily worthy of our worship. Can see where Mani gets his warped ideas from, can't you..?
