I cannot say nor agree that this hypothetical situation will ever come to furition; It is not within Gods plan to do so.
Can any of us say, this side of salvation, that we would obey these things in their contemporary setting? Not without assistance from God Himself, no, and to copletely "keep" them in the ideal meaning of "keep?" No one has done this except for Christ.
Gods coming kingdom, I do not believe, will have such laws in place, having been fulfilled by Christ Himself.
I think the hypothesis here to be a trap in a sense as to if a person says "No," then ones heart is judged as being "not right with God then." This is an unfortunate accusation really, as this situation will never occur inb the first place.
I think for the most part the majority here love the Lord, and are thankful to not be under the curse of the Law, to fulfill it.
If I am deemed and judged as one whose heart is just not right, not as holy as anothers due to my answer here, then sobeit.
- Peace
