The general concept Jesus is speaking about here is that through cause and effect and patterns we know what will happen in the physical world in regards to the weather. Predicting the weather in the next few hours based on what we see and feel in the atmosphere is possible.
Similarly, the Old Testament reveals a lot about Jesus’ first coming. Any Jew could have studied the Bible and looked at what was happening in John the Baptist’s and Jesus’ ministry to know that the Messiah had come as the Lamb of God. But most did not. Thus, they deprived themselves of knowing the needed truth to make a good and right decision.
The future would be bleak for the generation that rejected the Messiah. A war with Rome that would lead to the nation’s destruction would come. A war that Israel would not recover from for almost two thousand years. The result for generations of Jews that would follow them would be rejection and persecution from one nation after another. Jesus’ rebuke to the crowd was a warning to not reject him as the Messiah and the result their rejecting would have. Jesus called them hypocrites.
Who is the modern hypocrite? The modern hypocrites do not study the Bible, pray, meditate, and see what is going on in the world around them. They do not seek God’s plans from theirself through personal study, prayer, and meditation. Their only chance to gain understanding and see from God’s perspective is from what other people tell them is in the Bible the few days they go to church, but even then something else is on their mind. They do not study themselves. They will be surprised when they experience what they did not prepare for.
