29 Two sparrows sell for a coin of small value, do they not? Yet not one of them will fall to the ground without your Father’s knowledge. 30 But even the hairs of your head are all numbered. 31 So have no fear; you are worth more than many sparrows.
It is estimated by man that there are an average of 100,000 hairs on a human head. Some more than others. The number is also not set, but varies by age, as many are well aware.
The amazing fact of verse 30 is not that Jehovah knows the number of hairs on our head. That is an obvious given. If man can come up with an estimate of how many hairs we have, how much more so almighty God.
Jehovah knows the position, state and eternal history of every atom in the universe. This information is all registered in his Great Holy Database. So obviously, Jehovah “knows” the number of hairs on our head, as he knows the exact number of atoms in our body.
That he knows the number of them is not the point of this verse. Of course he knows the number.
The point is that he is interested in how many hairs are on our head. He takes note of this number. He has numbered them, an active verb.
The word “number” is a noun, at static thing, “an arithmetical value, expressed by a word, symbol, or figure, representing a particular quantity”. But it does not say he knows the number, it says he has “numbered” them, a verb, an action. He has taken note of. He cares about.
It is more than just info stored in his Great Holy Database.
Since he actually cares about how many hairs are on our head, a rather small, inconsequential fact about us as a person, how much more so does he care about the thoughts and feelings of our heart. The pain, anguish, and hurt. The joy, happiness, and love.
It is saying that we as a person matter, that we mean something to him, he is keenly interested in us to the point that he numbers our hairs.
So, we can have no doubt that when we pour our heart out to him in prayer, he hears us, he takes not of it, he numbers our tears, of either pain or joy.
