I have to ask, why should everyone have children?
I would make a lousey parent. I absolutely can't stand kids.
Because it makes the good revrund and certain FReepers happy. Haven't you been paying attention to the thread?
First let me say, that I don't necessarily agree that childless by choice married couples are sinners.
God gives us marriage partners, in part, so that we can experience a tiny measure of the great love and devotion that He has for us.
Becoming a mother or father, helps us to experience a small part of the love that God holds for us. I think about my love for my children, and I know that God loves me in the same way. I find it easy to forgive my children but sometimes it is hard to understand why God so easily forgives me. When I think about truly being a child of God, it makes more sense. Because I cannot imagine turning my back on my children, it helps me to understand how it is that God will never abandon me.
These relationships (spouses and parenthood), help us to better understand and relate to God. THAT is why he wants these things for us.
