Matthew 15:29-31 says
Jesus departed from there, skirted the Sea of Galilee, and went up on the mountain and sat down there. Then great multitudes came to Him, having with them the lame, blind, mute, maimed, and many others; and they laid them down at Jesus’ feet, and He healed them. So the multitude marveled when they saw the mute speaking, the maimed made whole, the lame walking, and the blind seeing; and they glorified the God of Israel.
It’s interesting to note the two highlighted words. The two words are distinct in the orginal Greek: Kullos (maim) and Cholos (lame) are separated, with clear distinction. Just pulling definitions from an English dictionary we see that:
Lame: Disabled so that movement, especially walking, is difficult or impossible.Maimed: badly injured, perhaps with amputation - maiming implies the loss or injury of a bodily member through violence.
In other words Jesus healed not only those unable to walk (who had all their body parts) but also those who were missing body parts. I know there are many who would claim that healing is more psychological than physical - mind over matter, believing that you can and so on - but it’s verses like this that clearly say it’s way more than that. Jesus came preaching the “Kingdom of God” - the rule and reign of God - and healing was an integral part of the message.
