Prophecy ought not make us fearful, but faithful. The analogy of a fig tree getting its leaves, indicating that summer is coming, indicates a different way of reckoning the seasons. Moderns like the day-and-hour concept of seasons. For instance, in the USA, summer 2016 begins Monday, June 20 at 6:35 PM EDT. We can also determine seasons by looking at plants and weather. In this way we speak of summer coming late or early. Jesus’ coming cannot be determined by the day-and-hour, but only by its nearness and it’s approach should spur us to readiness. The term “this generation” is not necessarily a length of time, but could also refer to fearful people attached to this world who resist the Gospel. That kind of people will not pass until Christ returns. Jesus encourages believers to be ready and in prayer.
