This is a question that some children likely ask at some point, many others probably wonder about it but don’t ask. My question is this: if your child asks this of you, what will your answer be?
The miracle of birth, whether it is a boy or a girl, is amazing. God takes a little from both of you and makes a new person who is not you or your wife but is entirely a person with a real personality, some more than others! This fact alone should push you in the direction of getting to know God more personally than any other.
I mean, before your first child is born there was just you and your spouse. You loved each other and lived your life, but when that first child comes along, boy does everything change! There are diapers, and formula, and worry about what is in this food, reading labels, making sure of their sleeping environment, the list could go on and on.
My point is this: if you didn’t know God before, then you NEED Him in every situation now! Not that raising children is bad but you do need His strength and guidance in any and all situations while raising them. They need to see God reflected in you every day, not the frustrated dad or mom coming home from work.
God created each of us for a purpose, sometimes it is being an example to our children. Actually, if God has gifted you with children, then being an example for them IS your purpose, everything else fades into the background. Your example to them and to the world is important because even if you don’t make an impact in the world, your child or children may have more of an impact than you could. So, make your example a good one.
