“The Pharisees also with the Sadducees came, and tempting desired him that he would shew them a sign from heaven. He answered and said unto them, When it is evening, ye say, It will be fair weather: for the sky is red. And in the morning, It will be foul weather to day: for the sky is red and lowring. O ye hypocrites, ye can discern the face of the sky; but can ye not discern the signs of the times?”- Matthew 16:1-3.
In the aforementioned text, Jesus Christ was berating the Pharisees and Sadducees for being able to discern and predict weather conditions at the expense of the word of God that gives life. (John 8:31, 32) It is this misplacement of priorities among the Jews that triggered the saying that they were “blind guides, which strain at a gnat, and swallow a camel”. (Matthew 23:24) If they could spend time studying the weather then they should be even more diligent in making out time to study the word of God and to know of its fulfillment.
Similarly, in the time of Jeremiah the Prophet, the Almighty Father lamented thus: “Yea, the stork in the heaven knoweth her appointed times; and the turtle and the crane and the swallow observe the time of their coming; but my people know not the judgment of the LORD” (Jeremiah 8:7) We should use our time well by being spiritually-minded so as to gain: “…manifold more in this present time, and in the world to come life everlasting”. (Luke 18:30). Saint Paul also said: “For to be carnally minded is death; but to be spiritually minded is life and peace” –Romans 8:6.
For all believers, reading of the Scriptures regularly, singing melodious songs of praises to God, meditating on the word of God, striving to practice the commandments of God and to “pray without ceasing” as Scriptures enjoin us is making good use of our time. – Ephesians 5:19, 20; Colossians 3:16; 1Thessalonians 5:18; etc.
