Faith Pleases God

Hebrews 11:6 tells us that without faith it is impossible to please God. Romans 10:17 tells us that faith comes from hearing the Word of God.

Mark 11:22:24 tell us how faith works. "So Jesus answered and said to them, "Have faith in God (or Have the faith of 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, bleieve that you receive them, and you will have them."

We are to say what we want (only say what we are in agreement with the Word of God).
We are not to doubt in our heart that what we have said will come to pass.
We are to believe that what we have said is already ours.
We will have what we said.

For example,
We tell sickness/pain to leave our body in the name of Jesus.
Since Isaiah 53:4-5, Matthew 8:16-17 and I Peter 2:24 tell us that Jesus came and healed us already, we know it is God's will for us to be healed. So we do not doubt the Word of God. According to I John 5:14-15 we know that this is the confidence we have in Him. If I ask anything according to His will (According to the Word of God it is God's will for us to be healed.), He hears me, if I know that He hears me, what ever I ask, I have the petition that I have asked of Him.

Pain has to leave and by Jesus stripes we were healed.
