"I do not know how to speak for I am only a youth," Jeremiah 1:6.
Ever listen to a young man talk about some piece of wisdom he's learned through his years? Afterwards, ever talk with fellow cronies about the young man's arrogance to presume wisdom? Yeah? Well, this scripture's talking about a young man likewise concerned. Just a newbie. But then, God. Yes, God. God says to the kid, To whomever I send you, you go. Don't fear them. Whatever I tell you to say, you say. I consecrated you before you were born. I appointed you. I am with you. I deliver you. I put my words in your mouth. I make you a prophet. The thing about God is that his word doesn't depend on our hierarchical (or geriatric) structures. Arrogance comes in not listening to God's word, whomever his medium.
As we visit with a brother or sister today, diligently, we compare any voiced message against God's Good Book, not against our age. And, together, young and old, we give thanks to God for the faithful testimony of his word.
