It could be said that Jesus was the most confident man that has ever lived. His triumphal entry into Jerusalem was a significant event because it demonstrated that Jesus’ claim to be God had been proven beyond a reasonable doubt. The prophet Isaiah said of Jesus Christ, “Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel” (Isaiah 7:14). A key prophecy about the arrival of Israel’s Messiah was that he would be identified as the “King of the Jews” (Matthew 27:11). Zechariah said of this man, “Rejoice greatly, O daughter of Zion; Shout, O daughter of Jerusalem: Behold, thy King cometh unto thee: He is just, and having salvation; lowly, and riding upon an ass” (Zechariah 9:9). Jesus fulfilled this prophecy when he rode into Jerusalem on a donkey on what is now referred to as Palm Sunday.
Jesus’ arrival in Jerusalem was a noteworthy event because he was defying the religious authorities that were planning to kill him. Everyone was paying attention to what Jesus was doing and probably knew something spectacular was about to happen. Many of the people that met Jesus in Jerusalem had seen him raise Lazarus from the dead (John 12:17-18). Even the religious leaders said among themselves “behold, the world is gone after him” (John 12:19). The key issue at stake was Jesus’ authority (Mark 11:28). If Jesus was God, then he had the right to rule over the nation of Israel and was accountable to no one but his heavenly Father. The Apostle Paul later described Jesus as “the image of the invisible God, the firstborn of every creature” and said of his authority, “for by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: and he is before all things, and by him all things consist” (Colossians 1:15-17).
In the midst of all that was going on, Jesus let his disciples know that his human needs still had to met. Matthew tells us, “Now in the morning as he returned into the city, he was hungered. And when he saw a fig tree in the way, he came to it, and found nothing thereon, but leaves only, and said unto it, Let no fruit grow on thee henceforward for ever. And presently the tree withered away” (Matthew 21:18-19). Jesus used this opportunity to teach his disciples about the power of faith and about the authority they had received from him. Jesus said:
“Have faith in God. Truly, I say to you, whoever says to this mountain, ‘Be taken up and thrown into the sea,’ and does not doubt in his heart, but believes that what he says will come to pass, it will be done for him. Therefore I tell you, whatever you ask in prayer, believe that you have received it, and it will be yours.” (Mark 11:22-24, ESV)
Jesus’ command pointed out that believing was an essential element of answered prayer. The only thing that could keep his disciples from getting their prayers answered was doubt. The Greek word Jesus used that is translated doubt diakrino means to separate thoroughly (G1252). Jesus was probably telling his disciples that doubt was going to be the result of being separated from him. The reason Jesus was able to act with complete confidence was because he and his Father were one, spiritually there was literally no distance between them. The Greek verb translated received in Mark 11:24, lambano actually means to take or objectively “to get hold of” (G2983). This may mean that our confidence in receiving what we pray for comes from a recognition that we are just as close to Jesus as he was to his Father. Jesus prayed that all believers would be united with him just before he was arrested. He said, “Neither pray I for these alone, but for them also which shall believe on me through their word. That they all may be one; as thou, Father, art in me, and I in thee, that they may be one in us: that the world may believe that thou hast sent me” (John 17:20-21).
