In other words, pro-creation is not the purpose of sex. But there are other reasons some resort to abortion other than promiscuity. 'Let the little children come to me' does not sound like Jesus would approve of abortion.
In this historical context...by the way...where hormonal pills enable women to reduce the risk of unwanted pregnancies by 2%...abortion seems an anachronistic issue to me.
I am not saying that one shouldn't have sex to enjoy life. I am just saying that abortion is extremely avoidable.
