God knows His children in great detail. He doesn’t refer simply to Jeremiah, but to Jeremiah, son of Hilkiah, etc. etc.
God knows every one of our particulars. He’s privvy to our likes and dislikes; victories and failures; hidden strengths and secret sins. His love goes deeper than all of them, so that when we’re told God welcomes us into His family just as we are, we can be assured that He realizes what He’s saying.
To God I’m not just Steve. I’m Steve, son of Ruel, one of the maintenance crew of the city of Attleboro, a small town in the state of Massachusetts. He won’t mistake me, therefore, for some other Steve. Instead, He loves me right down to the details.
