Mark 2:1-12, John 5:1-16

It seems that in many cases that physical illness or ailments have a strong connection to spiritual illness or ailments. When they brought one sick with palsy, when -

"...they uncovered the roof where he was: and when they had broken it up, they let down the bed wherein the sick of the palsy lay.
5 When Jesus saw their faith, he said unto the sick of the palsy, Son, thy sins be forgiven thee." (New Testament Mark 2:4 - 5)

After his sins were forgiven, the Savior said -

"...take up thy bed, and go thy way into thine house.
12 And immediately he arose, took up the bed, and went forth before them all..." (New Testament Mark 2:11 - 12)

You can sense that this healing not only required faith, but also repentance for which he was told his sins were forgiven. It was then, the one with palsy was physically healed.

We see this with Zeezrom as he -

"...lay sick at Sidom, with a burning fever, which was caused by the great tribulations of his mind on account of his wickedness, for he supposed that Alma and Amulek were no more; and he supposed that they had been slain because of his iniquity. And this great sin, and his many other sins, did harrow up his mind until it did become exceedingly sore, having no deliverance; therefore he began to be scorched with a burning heat." (Book of Mormon Alma 15:3)

In this repentant state -

"...Alma said unto him, taking him by the hand: Believest thou in the power of Christ unto salvation?
7 And he answered and said: Yea, I believe all the words that thou hast taught.
8 And Alma said: If thou believest in the redemption of Christ thou canst be healed.
9 And he said: Yea, I believe according to thy words.
10 And then Alma cried unto the Lord, saying: O Lord our God, have mercy on this man, and heal him according to his faith which is in Christ.
11 And when Alma had said these words, Zeezrom leaped upon his feet, and began to walk..." (Book of Mormon Alma 15:6 - 11)

James taught -

"Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord:
15 And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him." (New Testament James 5:14 - 15)

At the pool of Bethesda -

"...a certain man was there, which had an infirmity thirty and eight years." (New Testament John 5:5)

Whom said to the Savior -

"...Sir, I have no man, when the water is troubled, to put me into the pool: but while I am coming, another steppeth down before me." (New Testament John 5:7)

The Savior answers -

"...Rise, take up thy bed, and walk.
9 And immediately the man was made whole, and took up his bed, and walked..." (New Testament John 5:8 - 9)

As you read further, you would have to assume that he was a repented, faithful person for -

"Afterward Jesus findeth him in the temple, and said unto him, Behold, thou art made whole: sin no more, lest a worse thing come unto thee." (New Testament John 5:14)

It appears in these many verses that healing is not based on faith in Christ alone, but a demonstration of that faith through true and obedient repentance receiving forgiveness of their sins.
