Ephesians 4:28 doesn’t explain why we should work hard. But its imperative grows out of the broader biblical understanding of work. You and I as human beings were created to work, to use our full capacities in order to ensure that God’s creation functions as it is supposed to, leading to fruitful living for all creatures (Genesis 1:27-28). Of course when sin entered in work became more difficult and painful. Yet, this does not mean that all hard work is wrong or to be avoided. In fact, some of the most rewarding experiences of life come as we invest our full energies in a worthwhile project.
