The Withered Fig Tree 
20In the morning, as they went along, they saw the fig tree withered from the roots. 21Peter remembered and said to Jesus, "Rabbi, look! The fig tree you cursed has withered!"

22"Have faith in God," Jesus answered. 23"I tell you the truth, if anyone says to this mountain, 'Go, throw yourself into the sea,' and does not doubt in his heart but believes that what he says will happen, it will be done for him. 24Therefore I tell you, whatever you ask for in prayer, believe that you have received it, and it will be yours. 25And when you stand praying, if you hold anything against anyone, forgive him, so that your Father in heaven may forgive you your sins."

The Authority of Jesus Questioned 
27They arrived again in Jerusalem, and while Jesus was walking in the temple courts, the chief priests, the teachers of the law and the elders came to him. 28"By what authority are you doing these things?" they asked. "And who gave you authority to do this?"

29Jesus replied, "I will ask you one question. Answer me, and I will tell you by what authority I am doing these things. 30John's baptism—was it from heaven, or from men? Tell me!"

31They discussed it among themselves and said, "If we say, 'From heaven,' he will ask, 'Then why didn't you believe him?' 32But if we say, 'From men'...." (They feared the people, for everyone held that John really was a prophet.)

33So they answered Jesus, "We don't know."
      Jesus said, "Neither will I tell you by what authority I am doing these things."
