Yes. Mormons believe each one of us is an eternal being. Before the creation of the world, we existed as “intelligences” in the universe. God created us spiritually, and we existed as His spirit-children until we obtained physical bodies at birth into mortality. At death, our spirits and bodies separate. We are then spirits again until the resurrection when our spirits and bodies are joined perfectly and eternally. That is why Mormons say we are literally children of God and that He is literally our Father. However, we believe exactly as you do, that we become the children of God and Christ when we covenant to be His disciples. So these two ideas are not in conflict. Although we are all the children of God in a spiritual sense, we must use the agency He has given us to choose Him in mortality and bind ourselves to Him in eternity.

So this is confusing. The Bible says we are not children of God but can be adopted if people believe in Jesus and get baptized. Mormons believe people are already Gods children. Can you explain the discrepancy?
Thank you.
