And Jesus answering saith unto them, Have faith in God. For verily I say unto you, That whosever 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 11:22-23
And Jesus said unto the centurion. Go thy way; and as thou hast believed, so be it done unto thee. And his servant was healed in the selfsame hour. Matthew 8:13
And I say unto you, Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you. For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. Luke 11:9-10
Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much. James 5:16
