Extract the answer to the question from the following context. Question: What do Jehovah's Witnesses think about the baptism someone had as a baby? Context: Baptism is a requirement for being considered a member of Jehovah's Witnesses. Jehovah's Witnesses do not practice infant baptism, and previous baptisms performed by other denominations are not considered valid. Individuals undergoing baptism must affirm publicly that dedication and baptism identify them "as one of Jehovah's Witnesses in association with God's spirit-directed organization," though Witness publications say baptism symbolizes personal dedication to God and not "to a man, work or organization." Their literature emphasizes the need for members to be obedient and loyal to Jehovah and to "his organization,"[note 2] stating that individuals must remain part of it to receive God's favor and to survive Armageddon.
The answer to this question is:
not considered valid
