The vast majority of unsaved Americans do not need convincing that child-killing is wretched and immoral. What they do need convincing of is that abortion is child killing. Likewise, the vast majority of unsaved Americans do not need convincing that it is wrong to tear people's arms and legs and heads off, but they do need convincing that abortion does just that, four thousand times a day in this country. Thank God that so many of the people who reject Him as Creator and Saviour still have enough of His law written on their heart to govern their actions and inform their morality (at least as it applies to murder). What this means for us is that the major obstacle keeping most people on the "pro-choice" side is not so much moral as educational. We are not trying to preach them into a "new" morality, we are educating them towards a more consistent application of the morality they already have in place (one that condemns killing innocent people).
