I do not beleive that God asks men to do what they can not do.
For the unregenerate you claim the "repent" command as though some can not.
Well I would like to look at something if I may.
To the Jewish nation God commanded that they keep all the law. - They could not.
And even told them to be Holy as God is Holy, but they didn't have the Spirit to enable.
They did not have the empowering of the Holy Spirit be "ABLE" to do any of this.
With God all things are possible!
Now what about Believers who have the Holy Spirit and spiritual understanding.
Surly God would never command them to do what they are "unable" to do.
God commanded that we love Him with all our heart, mind, and strength
God commanded that we are to love the brethren.
God commanded that we "Be Holy -JUST AS- God IS Holy" - Be holy just like God IS
God commanded the we are not to sin anymore.
Now I ask you, name ONE believer that has EVER done one or all of these three of many commands without fail in the sense of its scriptual definition and literal consistancy.
I can tell you the answer - NOT ONE, EVER has lived.
So why not!? I thought we are empowered and filled by the Spirit of God and by Him we can do all things through Christ who strengthens us. Yes, this is true. But is God looking for perfection. He asks of His own the same that He asks of them who are not.
Is God asking us to actually be perfect as He is? I don't believe so.
But is showing that we are responsible to live up to that standard of Himself, and if responsible to live up to it it necessitates that we are able to do just what God requires of us. Either regenerate or unregenerate, when we are faced with what God reveals is in direct contention with Himself or Holiness, we are held accountable to that action or choice we make at that moment.
Like Bro. Bob stated. If God commands All men everywhere to "Repent" it necessitates that all men 'hear' that command and are responsible to respond. And "IF" they hear they ARE able to respond since the according to Calvinistic Theology - Only those who can hear are able to respond.
- Just some musing IMHO
