"And the prayer of faith will save the sick, and the Lord will raise him up. And if he has committed sins, he will be forgiven." James 5:15
What can faith do? Can it heal the sick? Can it cleanse sins? Can it be the factor that says heaven or hell for you? No not all! Faith does not have one merit on where you go. Let me break it down for you...
A man says that he has faith that he can move mountains and tells you he will. He looks to the snowy top and yells " Be overturned and crumble!" Nothing happens.
A woman goes to a hospital and looks at all the sick people and then says "My faith has healed you. You are no longer sick." The person never gets any better.
Last one. A man is standing before God and says " I have faith that today you will let me into heaven and I will see all of the beauty that rest just beyond this gate." He does not go there.
Now you might be saying that faith is what we need to get into those pearly gates and see the the glory of eternal life. I tell you only if you put it in the right thing. Faith avails nothing with out Jesus being the one you are faithful to and have faith in. Nothing else. Without God driving your faith you stand no chance of doing any of these things at all. God is the one has to move. You don't move the mountain on your own will. God is the one who lifts it up and cast it aside.
All the things that we accomplish in this world are driven by faith in something but the miracles are driven not by just faith but faith by God cause them to happen. Your faith is only as good as where you place the faith. If I have faith that I will be the one to cure the sick then I am mistaken. Only God heals. Faith is dead without Jesus being the one who your faith is given to.
