“Peter remembered and said to Jesus, Rabbi, look! The fig tree you cursed has withered! Have faith in God, Jesus answered. ” (Mark 11:21)
In the above passage the "fig tree" represents Israel. Peter was concerned about why Jesus had cursed Israel causing it to wither. Jesus had instructed Peter and the other Jewish disciples to pray as follows:
“...thy Kingdom come, thy will be done, on earth as it is in heaven...” (Matthew 6:9-13)
So Jesus cursing the fig tree was simply telling Peter that the Kingdom on earth will not come until Israel had first withered. After His resurrection Jesus spent 40 days instructing His Jewish followers about the Kingdom of God and the restoring of the Kingdom of Israel.
“He also presented Himself alive after His suffering, by many convincing proofs, appearing to them over a period of forty days and speaking of the things concerning the Kingdom of God...So when they had come together, they were asking Him, saying, Lord, is it at this time you are RESTORING THE KINGDOM TO ISRAEL? He said to them, it is not for you to know times or epochs which the Father has fixed by His own authority...And after He had said these things, He was lifted up while they were looking on, and a cloud received Him out of their sight. And as they were gazing intently into the sky while He was going, behold, two men in white clothing stood beside them. They also said, Men of Galilee, why do you stand looking into the sky? This Jesus, who has been taken up from you into heaven, will come in just the same way as you have watched Him go into heaven.” (Acts 1:6-11)
Many years later they became concerned about why Jesus had not yet returned to set up the kingdom and Paul wrote to encourage them...
”For I do not want you, brethren, to be uninformed of this mystery - that a partial hardening has happened to Israel until the fullness of the Gentiles has come in; and then ALL Israel will be saved; just as it is written, the Deliverer will come from Zion, He will remove ungodliness from Jacob. This is my covenant with them, when I take away their sins..." (Roman 11:25-32)
Jesus will return and establishes the Kingdom of Israel on earth which Revelation tells us will last one thousand years. Israel, the fig tree that Jesus temporarily cursed, will blossom again!
“Now learn the parable from the FIG TREE: when its branch has already become tender and puts forth its leaves, you know that summer is near; so, you too, when you see all these things, recognize that He is near, right at the door. Truly I say to you, this generation will not pass away until all these things take place..." (Matthew 24:33-34)
The generation we now live in saw that budding in 1948 with the establishment of the modern state of Israel. I expect Jesus to soon return and fulfill His promise to Israel.
