Joy and suffering are very personal things.
Rejoicing with those that rejoice and weeping with those that weep is generally done with those with whom we are close. It is most definitely limited to those situations we know about.
When our joy and our suffering is ours and it is great, we want the world to stop and it is a bit of a shock to us when it doesn’t. “Don’t they know?” “How can the world go on when so much of it has stopped for us?”
But even the best and kindest of us cannot rejoice and weep with everyone, simply because we do not know about their situation in life. Such knowledge is beyond our ability.
But not so with God.
Not even a sparrow falls to the ground without the Father. Jesus tells us that.
David focused on this knowledge of God and wrote the 139th Psalm about it.
He pondered the impossibility of going to a place where he could be out of the presence of God. Even his own thoughts were known by God before David even thought them.
He said such knowledge was too wonderful and too high for him. It was beyond his comprehension.
But what David realized about God was not just true for David. It is true for everyone. Such is the nature of the Bible. It is God’s book written to individuals which applies to every human being in the world.
Such knowledge and wisdom is beyond comprehension.
