Trying to catch up here. Reading all the posts since I posted last, I am thinking that this idea is being made much more complicated than it really is.
1. Christ tasted death for every man. Thus the wages were accepted by Him for every man. That is clear. There is no getting around it. One sacrifice for all. Done deal.
2. I am thinking that the justice was done for the sake of God as much for the sake of man. For God, it satisfied eternal justice. For man, it cleared the way for salvation.
3. Justice satisfied does not equal salvation. I think this is the sticking point, right? Salvation is contingent upon man's response to the truth according to Romans 1. It is contingent upon believing in Christ according to Him in John 3, and since He identified Himself as The Truth, that amounts to the same thing in the long run. If you want the truth, the Father will draw you to the Son, and the way is clear because justice has been satisfied.
4. So it's simply a matter of which side you want to be on. Calvinists say you wiill naturally want to be on the side of sin and rejecting God unless He works on you first. But I don't see the Bible saying that or implying it. I see the Bible pleading with men to believe, even to reason with God. To not harden their hearts (which means they don't start off hard). Men, biblically, have a free will to want whichever side they want. Truth or lie. Up to them. God has done everything that can be done to pave the way and show them where the truth is without forcing the issue one way or the othere.
5. Why would God NOT predestine who would be saved? Jesus gave us the answer when He gave us the two/one basic law: love. First God and then your fellow man/neighbor. Love is not love if it is programmed in (obedience means nothing, in the same way, if there is no choice about disobeying). It has to be a conscious, volitional commitment to another person or thing. We are certainly all commited to ourselves, and that is why Jesus told us to love our neighbor AS ourselves. We already love ourselves. We care DEEPLY about ourselves! Now, we cannot care, we cannot love, as God loves unless He indwells us. But He will not choose as a one-sided deal who He is going to indwell. We must open the door. We must want Him. Or at least, to begin with, want the truth. It will end up being the same thing later. But only because we will want to love will we be able to love. The want comes first. And that is why God judges the heart; the actions are simply the working out of the heart.
6. Jesus said people would die in their sins IF they didn't believe He is God. Their hearts are in rebellion against Him. Thus, the working out of their lives will be a working out of sin, in one form or another, as a lifestyle. That is why the Bible states that those who commit these sins cannot go to heaven. It is because of their hearts, where sin originates.
7. And that is why it will be believing and obeying which will result in heaven and rewards, respectively. The rewards can be won or lost or both depending on our obedience. Salvation, however, is for good because He has not lost one and none of us will be the first. Once we WANT the truth, He will begin to operate in our lives, first leading us to Himself, then giving us a new birth and then indwelling us to transform us into His own likeness.
8. At every step we are allowed say in the matter. This does not diminish his holiness or power or majesty, but only emphasizes it. He is bigger than all that, just as a father is bigger (on a much smaller scale, granted) than his toddler.
So justice satisfied clears the way through the Crucifixion.
Then, what will man do about that? Calvinism claims the word 'choice' but there is no choice really anymore than a horse has a choice between steak and oats. For a horse that is not a choice. But the Bible indicates man has a real choice which is not only available, but possible for every sentient adult at the very least. What are you going to do about Jesus?
What do you want? What are you seeking? You will find it.
At which door are you knocking? It will be opened to you.
What questions are you asking? You will find the answers.
What is it that you want?
That question is only possible because of the Crucifixion; because justice HAS been satisfied.
Refuse it and you stand condemned because of your own heart's refusal.
Accept it, believing and trusting, and you stand saved because of your own heart's acceptance.
Christ has done and will do everything.
Which do you WANT? That is what will end up as your salvation or condemnation -- your own choice in the matter.
On the side of the unsaved, it is the most difficult choice in the world, for it clearly means being willing to give up everything. This is why most have to reach the end of their proverbial ropes where nothing is left to them to give up! But God will even accept that, for which many of us thank Him deeply and continually.
But once saved, we wonder why it ever seemed so hard! It is so glorious and incredible on this side! Our lives need to show that, so that others will be attracted to 'this side' and want Christ, too.
