"For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith." (Mark 11:23 KJV)
Jesus said this. We have whatever we say we have in faith. Its that simple.
I challenge you to look into your own heart today and see what you are believing. Listen to your words, hear what you are speaking. For that is what you will continue to have and experience in your life.
