Mark 11:23-33

23 For verily I say to you, that whoever shall say to this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that the things which he saith shall come to pass; he shall have whatever he saith.

24 Therefore I say to you, Whatever things ye desire when ye pray, believe that ye receive [them], and ye shall have [them].

25 And when ye stand praying, forgive, if ye have aught against any: that your Father also who is in heaven may forgive you your trespasses.

26 But if ye do not forgive, neither will your Father who is in heaven forgive your trespasses.

27 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,

28 And say to him, By what authority doest thou these things? and who gave thee this authority to do these things?

29 And Jesus answered and said to them, I will also ask of you one question, and answer me, and I will tell you by what authority I do these things.

30 The baptism of John, was [it] from heaven, or from men? answer me.

31 And they reasoned with themselves, saying, If we shall say, From heaven; he will say, Why then did ye not believe him?

32 But if we shall say, from men; they feared the people: for all [men] counted John that he was a prophet indeed.

33 And they answered and said to Jesus, We cannot tell. And Jesus answering saith to them, Neither do I tell you by what authority I do these things.
