Work enables service. In one form or another, work empowers us to serve. And if you find yourself in an occupation that somehow doesn't seem to allow you to serve others directly, then direct a portion of your earnings to service. In addition to that, ask the Lord to show you how to serve those with whom and for whom you work. Work makes people productive.
Life is more than fun.
And life is more than just doing something. God has given us this precious gift and He expects that we expend and invest it wisely. He wants us to present Him with some fruit at life's end. Work can become drudgery. Work can darken life.
