The significance of this passage isn’t simply that God wasn’t alone but that Jesus, as part of the trinity has always been alive. He didn’t come to be when he entered Mary’s womb, he simply refashioned himself to fit inside her womb because He had to come speak directly to us. John pricks us with the truth and mystery of understanding the concept of the trinity on his opening passage here and this is something that we must broach with our kids. Can we fathom that Jesus always was and always will exist not just in singular form but as part of a mysterious trinity? Certainly not. But just because we can’t explain this phenomenon is no reason to keep from teaching our children about it.
Before they leave home, every Christian child must know that, while no mind can understand its reality, the trinity is central to the Christian faith because without it, Jesus would not have always existed. And we know that this is not true. So, the question for you is, do your kids know that even before the earth was formed, Jesus was alive?
