text: wwjd? if jesus did not have any children, then why do church attending people have more children? the graph in the link shows a correlation between church attendance and family size in european and north american nations.  http://www.nationmaster.com/plot/rel_chu_att/peo_hou_wit_mor_tha_5_peo/flag well, for basics, wwjd is more a "marketing tool" or buzzphrase than something to be applied in this context.   the goal was to have people examine how they treat others or how devoted they are to god, by comparing it to how jesus treated others or how he related to god.  obviously one can "emulate" jesus in terms of the sort of moral behavior they exhibit, without having to be a jewish man (kinda hard for the women), or being single, or being a wandering prophet, or having to be crucified by romans -- just as you might personally have a role model for yourself, yet you only emulate his attitude and ways of relating to others and outlook on life, not necessarily all the details of that mentor's circumstances in life.  as far as having kids, secular thought (generally) is that you have to be careful with your resources, you have to remain in control of your life, you don't want to take on more responsibility than you can handle, and so forth. kids are often "fit into one's life" rather than allowed to intrude randomly.  the conventional wisdom of general christianity is that kids are a blessing and a gift from god (often quoted is the verse that "children are like arrows; blessed is the man whose quiver is full of them), and that one is denying the providence of god by removing any possibility of ever having kids. this is the reason that the catholic church has that policy about "no birth control," although it's often not followed by the us church. in any case, kids are considered gifts rather than inconveniences to one's career or happiness, more of the time.   (personally, i think there's a line to walk between giving god room to work and being reproductively responsible with one's given resources.)
