The only part of the bible that will work for you is the part that you believe.
I heard this from Pastor Rod Parsely. SOme of you may know how he is, some thinks he is a little over the top but what I do know about him is that he believes in the word of God. What we have trouble with is believing that the bible is all that it says it is. Believing that we are what it says we are and that it can do what it says we can do. There is also another famous Pastor name Joel Osteen that before he starts his service he says "This is my bible it I am what it says I am and I can do what it says I can do.... I think quoting this is Awesome because we have to believe those very things. If we don't believe it wont work for us. The bible says all we need is faith of a mustard seed. So please hid this quote in your hearts and think of what it can do for you if you just believed it. I have seen what believing can do and I encourge you to do it today!
But the Scripture declares that the whole world is a prisoner of sin, so that what was promised, being given through faith in Jesus Christ, might be given to those who believe.
