I believe this, because of some things I have come to know (confirm) for myself. We lived with God, the father of our spirits, before we were born to mortality. We grew and learned, wanting to become more like Him, so he made a plan, sometimes called the Plan of Happiness, which we accepted, and by which we could come here, to get a physical body (which will be immortal later on), to learn from experiences of contrasts & good & bad, & to practice choosing right from wrong. After death (separation of the spirit from the physical body), we continue to have our same individual identity, we keep learning (everyone will have a chance to learn what they need, to choose for themselves), we await resurrection (physical immortality) and judgement, upon which we will be able to enjoy, to the extent that we were willing enough to obey God and follow the Plan, to progress and help others. Our enjoyments and progress are greatly enhanced when we learn more, and follow the good things we learn. He promised peace in this life, and the opportunity for eternal life in the world to come, if we do as he asks, but the choices are ours. (More at my site, like how I learned; nothing for sale.)
