Mark 11:24-33

24 Therefore I tell you, all things whatever you pray and ask for, believe that you receive them, and you shall have them.

25 Whenever you stand praying, forgive, if you have anything against anyone; so that your Father, who is in heaven, may also forgive you your transgressions.

26 But if you do not forgive, neither will your Father in heaven forgive your transgressions."

29 Jesus said to them, "I will ask you one question. 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 They reasoned with themselves, saying, "If we should say, 'From heaven;' he will say, 'Why then did you not believe him?'

32 If we should say, 'From men'"--they feared the people, for all held John to really be a prophet.

33 They answered Jesus, "We don't know." Jesus said to them, "Neither do I tell you by what authority I do these things."
