Usually when a baby is born it is impossible to know how his/her life will turn out despite having a good upbringing. What if the child, as he/she grows older embarks upon a life of crime and comes to have a terrible reputation among his/her peers and family and God? Can it be said that their birth turned out to be something to celebrate? On the flip side, when one has built up a fine or good reputation with others and with Jehovah God Himself, if that person dies, then his death can be said to be better than the day of his/her birth.
Also, the Bible verse at Romans 1:25 says: “They exchanged the truth of God for the lie and venerated (worshipped) and rendered sacred service to the creation (humans, animals, religious idols, religious paraphernalia and the like), rather than the Creator…”
Celebrating a person’s birthday is a form of worship that is rendered to them when we celebrate their birthday or the day of their birth. To venerate means to worship to put on high or exalt an object or human for the sole purpose of giving them recognition rather than the Creator. Many don’t realize that this is what they are doing when they celebrate their birthday or attend someone’s elses birthday.
Also, the Bible only mentions two birthdays inwhich on both occasions a death occurred. Please keep in mind that Jesus Christ never commanded his true followers to celebrate his birthday but rather to memorialize his death: (Luke 22:19).
Origen a 3rd century C.E writer wrote and insists that of all the holy people in the Scriptures, no one is recorded to have had a feast or held a banquet on his birthday…
Clearly the custom of celebrating birthdays does not originate in either the Hebrew or the Greek Scriptures. This is the reason why Jehovah’s Witnesses don’t celebrate or attend birthday parties.
