"Whatever you do, do all to the glory of God." (1 Corinthians 10:31b)
Do you recognize and appreciate your husband's creativity? Or do you criticize and demean his efforts? Instead of negativity, determine to be positive. Perhaps you can help your husband see that his efforts are an opportunity to glorify God.
Is your husband the "creative" type? Does he have any artistic gifts? What is that special "knack" he has? Affirm him for his handiwork--a hobby, music, gardening, tinkering with cars, working with wood, etc. Remember: Even if he doesn't measure up to your standards, praise his efforts. If your budget allows, buy him a book or magazine that will continue to encourage his special skill or talent.
If you have a hard time finding his "creative side," understand that men's creativity sometimes is related to their work. Find something he does to make his job run more smoothly or something he does that adds value to his work, and let him know that you have noticed.
