Emotions are one of the least reliable yet most influential forces in our lives. One day we are hopeful; the next, we hate. Despair at one time; delight, the other. Emotions are the surging, restless tides that keep ebbing and flowing, drawing us up, then pushing us down. The Psalms are a gyroscope, keeping moving things level, like a ship held steady in turbulent seas. This is why the Psalms often repeat the admonition to “look to the LORD and his strength; seek his face always. Remember the wonders he has done, his miracles, and the judgments he pronounced” (Psalm 105:4-5). To remember the strength of the Lord is to set the gyroscope spinning.
