Seeing as only 1/3 - 1/2 of fertilized eggs, when left alone, result in a live Birth, it would seem God is the single most successful practitioner of abortion out there. We simply call it "spontaneous abortion".
Certainly in the OT, He even commanded humans to do His aborting for Him (when His divine hand of doling out miscarriages to 1/2 - 2/3 of fertilizations apparently didn't fully satisfy Him):
Hosea 9:11-16 Hosea prays for God's intervention. Ephraim shall bring forth his children to the murderer. Give them, 0 Lord: what wilt thou give? Give them a miscarrying womb and dry breasts. . .Ephraim is smitten, their root is dried up, they shall bear no fruit: yea though they bring forth, yet will I slay even the beloved fruit of their womb. Clearly Hosea desires that the people of Ephraim can no longer have children. God of course obeys by making all their unborn children miscarry.
Numbers 5:11-21 The description of a bizarre, brutal and abusive ritual to be performed on a wife SUSPECTED of adultery. This is nothing less than an induced abortion to rid a woman of another man's child.
Numbers 31:17 (Moses) Now therefore kill every male among the little ones, and kill every women that hath known man by lying with him. (In other words: women that might be pregnant, which clearly is abortion for the fetus.)
Hosea 13:16 God promises to dash to pieces the infants of Samaria and the their women with child shall be ripped up. Once again, God kills the unborn, including their pregnant mothers.
2 Kings 15:16 God commands that the pregnant women of Tappuah (aka Tiphsah) to be ripped open.
For me, I'd choose against having an abortion, every and any time..
...But to suggest God is against the ending of all fetal life, in light if the scriptural testimony above, as well as His Divine decision that 1/2 to 2/3 of successful fertilizations must end in Miscarriage, is simply untenable.
Maybe it's only a problem when people do it apart from His orders to do it?
