"He answered them, “When it is evening, you say, ‘It will be fair weather, for the sky is red.’ And in the morning, ‘It will be stormy today, for the sky is red and threatening.’ You know how to interpret the appearance of the sky, but you cannot interpret the signs of the times." -- Matthew 16:2-3
It's quite amazing to see how many people are experts on the weather. They must be experts since they talk about the weather so much. Conversations begin with the current weather and continue on, focused on the forecast, as well as the weather patterns from last year at this time. They know the paths that the clouds make, but they don't know the Maker of the clouds.
The times have little changed since the days Jesus walked on the earth. There were those who were well versed in the movement of the heavens but they were completely unfamiliar with the Maker of the heavens. They could monitor the coming storm, but they were unable to recognize the coming Spiritual storm. As then, so now, people all around are blind to the "signs of the times".
While you may find it easy to start a conversation by discussing the weather, remember that the clouds of today will soon give way to the thunder of prophecy. We are watchmen my friend, and as the weathermen warn others that dangerous weather is approaching, so we need to warn our world that the judgment of God is riding the winds with certainty. Watch and point others to the "signs of the times" for their spiritual safety.
