Ephesians 5:16. “Redeeming the time, because the days are evil.”
My most-used commentaries all render the first part of this verse as “don’t waste time.” We are to make good and appropriate use of our time, not let it sift away like sand through our fingers.
Does that mean we can never rest? Of course not. God Himself rested on the seventh day; Jesus went across the Sea of Galilee to get away from the crowds; He also took a nap in the boat! Times of rest and relaxation are vital to our physical, emotional, and spiritual health.
The key here is the second statement: The days are evil. That is, moral turpitude abounds, and we need to seize every opportunity to share the gospel, thereby using the time for a good purpose. Again, we are to walk wisely, carefully, and profitably.
