Here’s how Bojidar Marinov answers the question asked in the title.
“Is abortion our national sin, or is it only the personal sin of those mothers and the abortion doctors?
If it is just personal guilt, we shouldn’t worry about God’s judgment. And our fight against abortion is rather a hobby. Whether babies are killed or not is not our personal problem.
But if it is national sin, on what basis do we project the personal sin of a few mothers and doctors onto the whole nation?
That’s right: COVENANTAL IDENTIFICATION. We are members of the same covenantal entity, the USA, and we all have our participation in the forming of its laws. And because of that, if and when God decides to bring judgment on America for her national sin of abortion, we all will be the recipients of His wrath, whether we have personal guilt or not.
Same with the South African farmers. For three generations they identified as a separate group from the blacks; and they used their political power to legislate identity policies of oppression, injustice, theft, and slavery. And what is worse, they used the name of Christ.”
