Mark 11:21-33

And Peter calling to remembrance saith unto him, Rabbi, behold, the fig tree which thou cursedst is withered away. And Jesus answering saith unto them, Have faith in God. Verily I say unto you, Whosoever shall say unto this mountain, Be thou taken up and cast into the sea; and shall not doubt in his heart, but shall believe that what he saith cometh to pass; he shall have it. Therefore I say unto you, All things whatsoever ye pray and ask for, believe that ye receive them, and ye shall have them. And whensoever ye stand praying, forgive, if ye have aught against any one; that your Father also who is in heaven may forgive you your trespasses. And they come again to Jerusalem: and as he was walking in the temple, there come to him the chief priests, and the scribes, and the elders; and they said unto him, By what authority doest thou these things? or who gave thee this authority to do these things? And Jesus said unto them, I will ask of you one question, and answer me, and I will tell you by what authority I do these things. The baptism of John, was it from heaven, or from men? answer me. And they reasoned with themselves, saying, If we shall say, From heaven; he will say, Why then did ye not believe him? But should we say, From men—they feared the people: for all verily held John to be a prophet. And they answered Jesus and say, We know not. And Jesus saith unto them, Neither tell I you by what authority I do these things.
