Proverbs 18:9 says, “Whoever is slack in his work is a brother to him who destroys.” The Message translation phrases it like this: “Slack habits and sloppy work are as bad as vandalism.”
Whatever version you read, those are strong words and a dire warning. Let me offer my own paraphrase: “Not doing your best work or not giving your best effort is pretty much the same as intentionally messing up the project.”
This passage reminds me of Colossians 3:23: “Whatever you do, work heartily, as for the Lord and not for men…” How could anyone “work heartily, as for the Lord” and do it half-heartedly or sloppily?
I encourage you today that whatever you do—assembling automobiles, designing widgets, making pastries, creating websites, teaching children, waiting on tables, writing a sermon, changing diapers, or whatever—that you do it full out, not in a slack or half-hearted manner. Do your work heartily, as for the Lord.
