21Jesus answered and said to them, Surely I say to you, If you have faith and doubt not, you shall not only do this which is done to the fig tree, but also if you shall say to this mountain, Be removed, and be cast into the sea; it shall be done. 22And all things, whatever you ask in prayer, believing, you will receive.
7Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: 8For every one that asks receives; and he that seeks finds; and to him that knocks it shall be opened 9Or what man is there of you, whom if his son ask bread, will he give him a stone? 10Or if he ask a fish, will he give him a serpent? 11If you then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him?
12Verily, verily, I say unto you, He that believes on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father. 13 And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. 14If ye shall ask any thing in my name, I will do it.
