In Mormonism, many people ask members of the Church of Jesus Christ of Latter-day Saints why they do baptisms for the dead. I am here to tell you why.
Jesus Christ taught us that baptism is essential to the salvation for everyone who has ever lived on earth. Many people, however, have died without being baptized, or have been baptized without proper authority. God, being merciful, prepared a way for everyone to receive the blessings of baptism. By performing baptisms in behalf of those who have died without baptism, Church members offer these blessings to the deceased. Individuals can then choose to accept or reject what has been done in their behalf. This is called doing baptisms for the dead. Church members willingly sacrifice some of their time to baptize for the behalf of the deceased person. Some people might think, "Why not just have one person just be baptized for all of those without baptism?" The reason is that the work must be done for each individual separately. Though tens of thousands of members are doing baptisms for the dead each week, around an average of five to fifteen each, there are hundreds of millions of names that need work done for them. Those in the next life whose names have been baptized for, can choose whether or not they accept being baptized and receive the gospel.
