I am a member of the Church of Jesus Christ of Latter-Day Saints. We have been commanded to multiply and replenish the earth. This week for our class we were to watch a video that discussing the fertility rate. In this video they asked people on the street what the right amount of children is to have. Each of these people answered with the same amount as they had in their family growing up, which was usually between one to three. After watching the videos we were to read the following quotes:

“There are multitudes of pure and holy spirits waiting to take tabernacles, now what is our duty?—To prepare tabernacles for them; to take a course that will not tend to drive those spirits into the families of the wicked, where they will be trained in wickedness, debauchery, and every species of crime. It is the duty of every righteous man and woman to prepare tabernacles for all the spirits they can.”
 - President Brigham Young

"You did not come on earth just to “eat, drink and be merry.” You came knowing full well your responsibilities. You came to get for yourself a mortal body that could become perfected, immortalized, and you understood that you were to act in partnership with God in providing bodies for other spirits equally anxious to come to the earth for righteous purposes. And so you will not postpone parenthood. There will be rationalists who will name to you numerous reasons for postponement. Of course, it will be harder to get your college degrees or your financial start with a family, but strength like yours will be undaunted in the face of difficult obstacles. 
“Have your family as the Lord intended. Of course it is expensive, but you will find a way, and besides, it is often those children who grow up with responsibility and hardships who carry on the world’s work. And, John and Mary, do not limit your family as the world does. I am wondering now where I might have been had my parents decided arbitrarily that one or two children would be enough, or that three or four would be all they could support, or that even five would be the limit; for I was the sixth of eleven children. Don’t think you will love the later ones less or have few material things for them. Perhaps like Jacob, you might love the eleventh one most. Young people, have your family, love them, sacrifice for them, teach them righteousness, and you will be blessed and happy all the days of your eternal lives.“
 - President Spencer W. Kimball (in an open letter to all young couples, found here in the Ensign, June 1975)

Just a little background on where I come from. I am the ninth of eleven children which is a blessing and a miracle. This is why it is a miracle. When my mom was pregnant with the second child my dad had lymphosarcoma and the doctor told them they wouldn't be able to have any more children. They prayed and asked Heavenly Father if it be right that they would be able to have as many children as He was willing to send. After that they had nine more children. I grew up in a small home that was about 1100 square feet. It had three bedrooms, and only one bathroom. We shared everything, we were really close and we each took away from that experience that family is very important not only to us but in the divine plan of things. I know that not everyone is able to have children, but I also know that those who are willing and rely on the Lord for help and guidance will be blessed to take care of the Lord's choice spirits. I know that having a family will have many learning opportunities for growth and trials. I know that it will not come easy, but it is definitely worth the time and effort.
