Kill, you’ve made a good effort and articulated yourself well here. You’ve argued that the ramifications for our various acts are far-reaching. And that is certainly true. And I know you’d like for this line of reasoning to be sufficient to establish that our acts are infinite after all.
By “finite” is simply meant limited. So, for example, when my child does something loving towards me does that satisfy for all time her obligation of love towards her father? I don’t think anyone would say it does. Nor does it satisfy my ongoing need for her love. (This same logic would apply to her offenses towards me.) So now we move the thought-experiment to the level of human vis-a-vis the divine. When I love Christ once does that satisfy for all time my obligation to love him? Again, I don’t know anyone who would suggest that it does. The admonition to obey his commandments (“if we love him”) extends over a lifetime for those who’ve known Him from a young age. There is no “once for all” with regard to our actions. And the same would hold for our offenses. Thanks be to God that forgiveness is possible!
So, you try to see things from God’s perspective then? That’s excellent and also precisely what I’ve been trying to get folks here to do in this thread. The Scriptures make the point very plainly and repeatedly that mercy trumps judgment. Mercy is a higher good than justice. Christ, on the cross, does satisfy the need for divine justice to be appeased. So the justice of God gets satisfied through the divine act of love. It took love to satisfy that requirement for justice. And since God himself is the only actually infinite Being who exists, that loving act can have infinite application. All that remains is for each individual human to be pursued by God and loved by God enough. His mercy endures forever, and forever is a mighty long time. Peace be with you Kill.
