If your Handicapped (Amputee, Paralyzed, Developmentally challenged, Aspergers, Epileptic, or any other sort of disability), you are defying God by walking to the altar.
Leviticus Chapter 21 versus 16 to 23
16And the LORD spake unto Moses, saying,
17Speak unto Aaron, saying, Whosoever he be of thy seed in their generations that hath any blemish, let him not approach to offer the bread of his God.
18For 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,
19Or a man that is brokenfooted, or brokenhanded,
20Or crookbackt, or a dwarf, or that hath a blemish in his eye, or be scurvy, or scabbed, or hath his stones broken;
21No 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.
22He shall eat the bread of his God, both of the most holy, and of the holy.
23Only 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: for I the LORD do sanctify them.
