Will Israel have to work hard to rebuild the nation after the tribulation?
No. Israel will not have to work by the sweat of their brow to rebuild the nation after the tribulation. By the time they enter the Kingdom, everything will be prepared and ready, just as breakfast was ready for the disciples on shore.
Les explains that the Kingdom will be on earth with Jerusalem as its capital, and Israel will be the top nation of the nations. By the time the nation is brought into that Kingdom experience, everything will be ready. They will not have to work by the sweat of their brow to get the nation restored after tribulation. Everything will be ready, even as breakfast was when they came to shore. The net is full, and not a single fish is lost, showing that not one single Jew will miss the end gathering for the Kingdom. This contrasts with Luke chapter 4, when the net broke and the fish got away, which was indicative of Israel's history when nothing really jelled for them and they never enjoyed all the promises God had given.
