Sickness and disease is NEVER God's will.
No it doesn't take any more faith to serve God when one is sick. Our faith should be sufficient to receive our promised healing and not to rebuff it. God desires us to be well so that we can serve Him fully without reservation or hindrance.
There is no EXTRA faith required for healing. It is provided in the atonement, and all we need to do is learn to appropriate it from our born again spirits into our physical bodies.
Really? You will then need to explain Daniel 4:28-37 for all of us............
28 All
this came upon King Nebuchadnezzar. 29 At the end of the twelve months he was walking about the royal palace of Babylon. 30 The king spoke, saying, “Is not this great Babylon, that I have built for a royal dwelling by my mighty power and for the honor of my majesty?”
31
While the word was still in the king’s mouth, a voice fell from heaven: “King Nebuchadnezzar, to you it is spoken: the kingdom has departed from you! 32 And they shall drive you from men, and your dwelling
shall be with the beasts of the field. They shall make you eat grass like oxen; and seven times shall pass over you, until you know that the Most High rules in the kingdom of men, and gives it to whomever He chooses.”
33 That very hour the word was fulfilled concerning Nebuchadnezzar; he was driven from men and ate grass like oxen; his body was wet with the dew of heaven till his hair had grown like eagles’
feathers and his nails like birds’
claws.
Then what about........22 Chronicles 26:19-20/p>
19 Then Uzziah became furious; and he
had a censer in his hand to burn incense. And while he was angry with the priests, leprosy broke out on his forehead, before the priests in the house of the Lord, beside the incense altar. 20 And Azariah the chief priest and all the priests looked at him, and there, on his forehead, he
was leprous; so they thrust him out of that place. Indeed he also hurried to get out,
because the Lord had struck him."
