When married couples are physically able, they have the privilege of providing mortal bodies for Heavenly Father’s spirit children. They play a part in the great plan of happiness, which permits God’s children to receive physical bodies and experience mortality.
If you are married, you and your spouse should discuss your sacred responsibility to bring children into the world and nurture them in righteousness. As you do so, consider the sanctity and meaning of life. Ponder the joy that comes when children are in the home. Consider the eternal blessings that come from having a good posterity. With a testimony of these principles, you and your spouse will be prepared to prayerfully decide how many children to have and when to have them. Such decisions are between the two of you and the Lord.
As you discuss this sacred matter, remember that sexual relations within marriage are divinely approved. While one purpose of these relations is to provide physical bodies for God’s children, another purpose is to express love for one another—to bind husband and wife together in loyalty, fidelity, consideration, and common purpose.
