There is no law and no good action that will save a man’s soul. Grace through Jesus will. This is the message of the Gospel.
Now, will following Scriptural mandates benefit a nation? Absolutely, it would. But, again, what was put forth was basically that if Christians were more militant in enforcing Scriptural legal codes on the US, the USA would be better off.
To that, I replied...Christianity would not be better off. That isn’t what Christianity is. Christianity isn’t a law that is mandated.
It is a free will, opt-in grace through faith in Jesus who is a hammer-swinging Jewish revolutionary who grew up in a podunk town. He did miracles (even according to secular Jewish historians like Josephus). He raised the dead. He ate with sinners (including tax collectors). And, for all that He was killed and thrown into a cave. He was resurrected, which explains why the very men who deserted Him while He was alive, died for Him after the resurrection-denier would say He was dead.
He wasn’t dead. Men who won’t die for living men, won’t day for dead men. He was resurrected.
So, it would be foolish to be reductionist with the Gospel for the sake of a lesser, yet noble pursuit. I say that as a conservative, Patriot, and as a follower of Jesus.
