Picture what the sky looks like right before a bad storm. Jesus talked of men being able to discern the weather by looking to the sky: “It will be foul weather today: for the sky is red and lowering” (Matt. 16:3). The word “lowering” is from a Greek word that means “a dark or gloomy appearance.” You know what that looks like, right? 
That same Greek word is found only one other time in the New Testament. In Mark 10, Jesus told the rich young ruler what he needed to do to inherit eternal life (i.e., sell his possessions and give to the poor), and the man “was sad at this word” (Mark 10:22). The word “sad” is that same word that describes “a gloomy man who broods over unwelcome thoughts” (H.B. Swete). The words of Jesus were unwelcome to this young man and made him dark and gloomy.
In contrast is the psalmist who said, “I rejoice at Your word as one who finds great treasure” (119:162). When you read and contemplate the Lord’s instructions to you, are you gloomy at the word (like a storm cloud) or do you rejoice at the word (like finding a treasure)?
