My wife and I are working though the issue of "family planning" together. We have two wonderful children and plan to have more. The question is whether it is Biblically permissible to use contraception to (attempt to) control the timing of births. Up until this time we have used natural family planning and barrier methods, but we would like to consider the issue again. A few questions: 1. Do you have any recommendations to further study this topic? 2. Do you think contraception is permitted by God? Why? 3. If contraception is permitted, what grounds are permitted for usage (illness, finances, etc.)? 4. If contraception is permitted, what methods are permitted? Obviously not abortifacients, but are barrier methods allowed?
