First lets get something strait. Does God want people on crack? No. However, if you have sex without sufficient protection (such as a vasectomy) you are basically saying to God go ahead and give me a child. If you are on crack at the time of having sex then its your fault because you shouldnt have been doing that (the drugs) in the first place. However, the reasons for allowing the creation of the child can be about the same as for allowing people to be poor, and such things as that. If you have nothing bad in your life then why would you look to God? If you think you have it all then why would you bother thinking you need God? The creation of the child is not bad. The situation the parent is placed in is a very hard one usually, however, if nothing's hard then who seeks after God? Just because God gives you a child and you messed it up right from the start doesnt mean that God didnt have a reason for giving you the child in the first place. Also, if the parent chooses to throw the baby out then thats the parents choice. The parent did not trust in God, and instead trusted in his or her own judgment. Was it a sin to kill the baby? Yes. The life ceased to exist, and the person who made the decision of it holds the guilt for not having faith in God (plus the blood is on their hands.) Not that the other people involved dont hold guilt in it too. Good thing there's forgiveness for sins. Thank God for that.
I didnt say married people shouldnt have sex. Sex is obviously a VERY important part of a marriage. Not the most important, but still very important. What I am saying is that you should be prepared for a child, in the event you receive one. Leave it up to God whether or not He gives you one. If He does, consider it a blessing. If it ruins your career plans, then so what. Theyre meaningless anyway. There are so many more important things in life; and being part of the creation of a child is one of them. If you dont think you can handle a child, or you think you wont like one then just trust in God. He can always help. Is that so hard? However, if you dont trust in God, and you keep the child, then you can grow bitter towards the child. Is it Gods fault you are bitter towards your own child? No. God gives gifts. Its your choice what you do with them.
