He said to the crowd: “When you see a cloud rising in the west, immediately you say, ‘It’s going to rain!’ and it does. And then the south wind blows, you say, ‘Its going to be hot.’ and it is. Hypocrites! You know how to interpret the appearance of the earth and the sky. How is it that you don’t know how to interpret this present time?” Luke 12:57-59
Man puts a lot of time into knowing the weather but puts less time into seeing the signs of Christ and his return.
