Fifteen years after the work on the temple had been halted due to numerous oppositions that the exiles faced, God sent his word to the people of Israel. First through the prophet Haggai (Haggai 1) and then two months later through the prophet Zechariah (Zechariah 1), God spoke to the people commanding them to restart the work on the temple.
Jesus and John, both preached in a similar manner but their lifestyles were different. The former lived a normal life and the latter lived in the wilderness. However, not many people took their message. Maybe people went to John not to repent or to get baptized but to see how was he living and similarly, people might have gone to hear Jesus not because they wanted to know his message but probably to find fault in him.
