"You will show me the path of life. In your presence is fullness of joy. Happy are the people whose God is the LORD!" (Psalm 16:11a; 144:15b)
"A merry heart does good, like medicine." (Proverbs 17:22a)
It's hard to criticize others when we are enjoying their company. Instead of speaking negatively to your husband today, enjoy him! Encourage him! As you experience fullness of joy with God, share some of that joy with your husband.
Does your husband have a playful side? A great sense of humor? Is there a "little boy" that wants to escape from time to time, reflecting the joy in his heart?
This is a wonderful part of who he is, and a great strength. Let him know that you appreciate his joyfulness and his playful spirit. Find opportunities to join him in positive play times.
If your husband can sometimes be overly serious, coax him out occasionally for some play times. It will help him relieve stress and relax.
