There is no "excuse." There is the practice of law which attempts to render justice, but is deeply flawed on account of weakness we altogether cannot excuse before the Creator. The State should take seriously its authority to protect innocent life. But it has been corrupted. Nothing new.
The sword, born properly, will redound to peaceful life both here and in eternity. Those who abuse it, whether by abortion, thievery, or slander will face an end worse than death. It is these for whom prayer issues forth. The souls of every innocent slain child will be on the balance of judgment against those who willfully persist in evil. The Creator's earnest concern is that none of those descended from Adam and Eve be counted among them.
There are those who enter into labor in the vineyard at the last hour, who are not to be begrudged grace, but welcomed insofar as the Creator is incarnate in Christ, crucified and risen from the dead. The heart and mind of the Creator are steadfastly fixed on repentance and faith to the extent He took the form of a servant and was crucified in order to exchange our sin for His righteousness.
Foolish as it may appear to the world, no mother who aborts a child, or doctor who performs an abortion, is left out of this atonement, and so all are subject to hearing about it that they might repent and be saved. As to when and where this grace is preached and received, that is the Holy Spirit's work, not ours. Being creatures, who are we to discern or tell the Creator how and when to act? We only know what He has said and done, and it is very good.
But we live in reality, and so it may happen that the State applies corporal penalties to the practitioners of abortion, just as it does to the practitioners of murder and thievery. It is incumbent upon the State to protect innocent life.
The evil one will do all in his power to murder, and so usurps the State to his ends, and also wreaks havoc in the Church. But he is crushed and dismembered because Christ has made atonement for all sin, and He has defeated death by His resurrection, as attested by history. The evil one steps on his dick day and night, while the angels rejoice over such a great salvation rendered on behalf of poor, miserable sinners.
