I agree fully that [abortion and homosexual rights] are important moral issues which Christians must address. But when I went through the New Testament I could find very little related to either one. Both practices existed then, in a different and more egregious form. Roman citizen did not rely principally on abortion for birth control. The women bore their babies, then abandoned them by the side of the road for wild animals or vultures. Likewise, Romans and Greeks also practiced a form of same-gender sex; older men commonly used young boys as their sex slaves, in pederasty.
Thus in Jesus’ and Paul’s day both these moral issues asserted themselves in ways that today would be criminal in any civilized country on earth. No country allows a person to kill a full-term, delivered baby. No country legally permits sex with children. Jesus and Paul doubtless knew of these deplorable practices. And yet Jesus said nothing about either one, and Paul made only a few references to cross-gender sex. Both concentrated not on the pagan kingdom around them but on the alternative kingdom of God.
For this reason, I wonder about the enormous energy being devoted these days to restoring morality to the United States. Are we concentrating more on the kingdom of this world than on the kingdom that is not of this world? The public image of the evangelical church today is practically defined by an emphasis on two issues that Jesus did not even mention. How will we feel if historians of the future look back on the evangelical church of the 1990s and declare, “They fought bravely on the moral fronts of abortion and homosexual rights,” while at the same time reporting that we did little to fulfill the Great Commission, and we did little to spread the aroma of grace in the world? – Philip Yancey, What’s So Amazing about Grace?
