I discovered this hidden gem in Zechariah 10:7:
The Ephraimites will become like mighty men, and their hearts will be glad as with wine. Their children will see it and be joyful; their hearts will rejoice in the Lord.
In short, when a father is glad, his children will be filled with joy and will rejoice in God. Although it doesn’t say it in this verse, I’m certain from experience that the converse is also true. When I am depressed, my children hurt, too.
We dads need to remember that our calling is to be husbands and fathers long before we are called to let anything else impair our ability to perfect the callings of family.
