Jasvon.

If you have the Gift of Healing, Paul, then lay your hands on this child in the front and ask the Lord to heal him from brain damage and the tics he now has from the medications he's been taking. If the Lord answers your prayer for him, then I'll post pictures of EVERYONE I know here who needs a healing.
Jasvon, I don't do the healing, the LORD does.
If you believe me, then the child is healed.

I don't doubt the Lord can heal, Paul, and I don't doubt He can work through whomsoever He chooses to nor do I doubt there are people in the Body of Christ who have the Gift of Healing, as the Scriptures teach:
Those that believe, and are baptized, are saved.
If you can't do healing, then you have not your power from Jesus,
and you are not doing all He commanded. Are you.

The Priest was healed because he believed on me.

If you do indeed have the Gift of Healing, then I'll fall to my knees and ask the Lord for forgiveness for debating/arguing with you.
If God heals, then you'll repent?

That is the prevailing attitude of the Gentiles. Isn't it.
I know, if you repent, then God shall heal.

Let me just say, though, Paul, that you are very wrong to assume anyone's sickness is due to sin:
I believe the verse which said it,
and the verse you put was of a man born blind from birth, and he was not sick.

You're quick to find a verse to justify your beliefs,
but you should be more careful to read what they actually say,
and not use one verse to cast down another.
Just my humble opinion
`Paul

And it shall come to pass,
if thou shalt hearken diligently unto the voice of the LORD thy God,
to observe and to do all His commandments which I command thee this day,
that the LORD thy God will set thee on high above all nations of the earth:
And all these blessings shall come on thee, and overtake thee,
if thou shalt hearken unto the voice of the LORD thy God.
Deuteronomy 28:1-2

But this thing commanded I them, saying,
Obey My voice,
and I will be your God, and ye shall be My people:
and walk ye in all the ways that I have commanded you,
that it may be well unto you.
Jeremiah 7:23

Verily, verily, I say unto you,
If a man keep My saying, he shall never see death.
John 8:51
