[I chose not to have children due to my upbringing and because, to this day, I don't think I would have been responsible enough. I would not want to have the affect on a child that my parents had on us, so I chose not to have children. Now is that wrong, or is that being responsible?]

Also respectfully, I think if God leads you to do something then He's perfectly capable of managing your offsprings' number without you having to choose on your own. Either one trusts God and His directions and His desires in all areas of her life or one doesn't. I can't see how it can work both ways. I am sorry I didn't mean to offend you and I might just have misunderstood your reply ..
I am just a little mixed up when people say that God leads them to do this and that, and then they say they chose to not to have children because they want to be responsible. I guess if God really leads them to do something then He'd be perfectly capable to take care of the children issue too. He's the giver of the life and He can freely open and close the womb however it fits to His perfect plan. I am afraid many times we justify our own desire or choice of not having children - with God's higher calling. If there's truly a calling then He'll take care of the rest.
