Using Faith

"Have faith in God. For assuredly, I say to you, whoever says to this mountain, 'Be removed and be cast into the sea,' and does not doubt in his heart, but believes that those things he says will be done, he will have whatever he says.
Therefore I say to you, whatever things you ask when you pray, believe that you receive them, and you will have them.
And whenever you stand praying, if you have anything against anyone, forgive him, that your Father in heaven may also forgive you your trespasses."
Mark 11:22-25

What we say is as important as what we believe.

Speak to sickness and command it to be removed.

Believe that what we say will be done, and we will have what we say.

When we pray for healing, we believe and will receive.
We are to believe we receive at the time we pray, then it will be ours.

But, if we have anything against anyone, we are to forgive.
Failing to forgive can be a major hinderance to seeing our prayers being answered, blocking our prayers and even blocking our healing.
