“who do you think the ultimate judge of one’s behavior is?”
Ultimately God the father judges whether we have accepted the sacrifice of Jesus and whether we have endeavored to follow his law.
But I see nothing but folly in any attempt to implement Christian morality via the force of human law.
I can't agree with that. Our law once did reflect the Christian morality and normality behind it. Our whole law system had such basis, and the Declaration of Independence/Constitution had the substance of a Christian society. Our Founders expressed that in no uncertain terms.
The Holy Spirit, working through His loyal followers has restrained the Forces of Satan's earthly subjects, but the dam is cracking for lack of a plurality of Christian citizens to see their principles at least recognized and imitated by non-Christian citizens who see the benefit of them,
But I believe that soon the restraining force will be taken away when true believers are removed from the face of the earth and the full force of evil is poured out as never before. We ar seeing the beginning of that right now. To quote from the Bible:
"And now ye know what withholdethsuppresses evil that hethe antichrist might be revealed in his time. For the mystery of iniquity doth already work: only heThe Holy Spirit who now lettethrestrains will letrestrain, until heThe Holy Spirit be taken out of the way" (2 Thess. 2:6-7 KJV; explanatory superscripts added).
