Baptism and how the Church ensures that everyone can return home

In John, 3:5, it says: “Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God."  This bothered me greatly, because it didn’t make sense.  If we have a loving Father in Heaven, how could he allow one of his children to not return to him, just because they were unfortunate enough to be born into a situation where they didn’t get to know how to go to heaven?

The LDS Church is the only Church I know of that answers the question:  The Church teaches the doctrine of Baptism for the Dead. This is why it has the world’s largest database of everyone who has ever lived, plus it also has the most active ongoing effort at genealogy, so it can help families find their kindred dead.  In fact it performs, through its members, every ordinance that is necessary to assure that every soul who ever lived, will have the opportunity to return to the Father, and to live forever.
