20 The next morning as they passed by the fig tree he had cursed, the disciples noticed it had withered from the roots up. 21 Peter remembered what Jesus had said to the tree on the previous day and exclaimed, "Look, Rabbi! The fig tree you cursed has withered and died!" 22 Then Jesus said to the disciples, "Have faith in God. 23 I tell you the truth, you can say to this mountain, 'May you be lifted up and thrown into the sea,' and it will happen. But you must really believe it will happen and have no doubt in your heart. 24 I tell you, you can pray for anything, and if you believe that you've received it, it will be yours. 25 But when you are praying, first forgive anyone you are holding a grudge against, so that your Father in heaven will forgive your sins, too. " 26
27 Again they entered Jerusalem. As Jesus was walking through the Temple area, the leading priests, the teachers of religious law, and the elders came up to him. 28 They demanded, "By what authority are you doing all these things? Who gave you the right to do them?" 29 "I'll tell you by what authority I do these things if you answer one question," Jesus replied. 30 "Did John's authority to baptize come from heaven, or was it merely human? Answer me!" 31 They talked it over among themselves. "If we say it was from heaven, he will ask why we didn't believe John. 32 But do we dare say it was merely human?" For they were afraid of what the people would do, because everyone believed that John was a prophet. 33 So they finally replied, "We don't know." And Jesus responded, "Then I won't tell you by what authority I do these things."

Commentary on Mark 11:19-26
(Read Mark 11:19-26)
The disciples could not think why that fig-tree should so soon wither away; but all wither who reject Christ; it represented the state of the Jewish church. We should rest in no religion that does not make us fruitful in good works. Christ taught them from hence to pray in faith. It may be applied to that mighty faith with which all true Christians are endued, and which does wonders in spiritual things. It justifies us, and so removes mountains of guilt, never to rise up in judgment against us. It purifies the heart, and so removes mountains of corruption, and makes them plain before the grace of God. One great errand to the throne of grace is to pray for the pardon of our sins; and care about this ought to be our daily concern.
Commentary on Mark 11:27-33
(Read Mark 11:27-33)
Our Saviour shows how near akin his doctrine and baptism were to those of John; they had the same design and tendency, to bring in the gospel kingdom. These elders did not deserve to be taught; for it was plain that they contended not for truth, but victory: nor did he need to tell them; for the works he did, told them plainly he had authority from God; since no man could do the miracles which he did, unless God were with him.
