Which heart gets stirred?
Our hearts get stirred; we cannot move towards Him without His stirring. But we can still refuse to be stirred. It may seem like a subtle distinction but in any case evil/sin, opposition to God's will, could not even exist in His creation
unless for this freedom. And reconciliation and salvation cannot occur unless for His grace, His moving us towards Himself. But man's basic nature with his freedom remains, however compromised and weakened by the Fall, and God's patient workings with man through the centuries and His working in us now have never had the purpose of destroying or denying that freedom that He granted in the beginning but rather of appealing to and eliciting it to be used in the right way, in alignment with
His will. Again, He's prepared us, He's educated us; He's the Potter who's not, merely and reluctantly, saving a part of His otherwise worthless wretches known as human beings but rather who's
producing something, molding something of higher value than He started with, knowing the beginning from the end and having the big picture in mind that we can now only begin to understand in part.
And a major aspect of that "something" is our own participation, however weak at first, beginning with faith, a response to grace that is both a gift and a very human act. That movement, that choice, is the basis of man's
justice, that which makes him right in God's eyes as it establishes the vital, life-giving connection or union with Him that we were made for, that constitutes the right order of things for man. So right now, in this world,
our job is to begin to come to recognize our need for God, and this life is a perfect school for us to learn of that need the hard way, by the experience of life in a world effectively separated from Him, the life that Adam desired, that he thought would be better. He was wrong and we're here to find that out, and, again, our personal experience along with revelation/knowledge and grace all help serve to bring us to that point. He calls; we respond...or not. Or not now, maybe later. We're an obstinate bunch but someday "every knee shall bow"-and remain bowing, willfully, out of the love that has been wrought in their hearts as they've learned the perfect rectitude of that love and of His worthiness of it. God
wants us to love as He does:
freely, intensely, knowing why, worshiping in Spirit and truth, even as this is not fully realized until the next life, but having finally
chose good over evil as we've come to distinguish between the two, having chose
Him who, alone, can bring triumph over that evil.
If not for the necessity of humans coming to learn these things for themselves this whole post-Edenic drama of human history that's being played out, up to and including Christ's passion, sacrificial death, and resurrection and through to this day, would have no real purpose; God might as well have just stocked heaven with the elect and hell with the rest from the beginning.
