The Bible nowhere forbids birthday celebrations. While Scripture clearly warns against narcissism, self-indulgence, and pagan customs, it does not condemn the simple act of marking the day of one’s birth with joy and thanksgiving. In fact, several passages suggest that birthdays—and the remembrance of one’s birth—are naturally associated with rejoicing, family gathering, and God’s blessing.
1. Birth of Isaac
“The child grew and was weaned, and Abraham held a great feast on the day Isaac was weaned.” (Gen. 21:8)
While this verse refers to a weaning feast rather than a formal “birthday party,” it clearly shows that marking a key stage in a child’s life with celebration is entirely appropriate. In the ancient world, weaning often happened around the age of two or three, and this milestone was a moment of great joy and gratitude to God, since infant mortality was high.
Hence, there is nothing inherently wrong with setting aside one day a year—our birthday—to rejoice in God’s preservation and goodness. Scripture shows God’s people celebrating significant life moments in a way that honors Him. A birthday celebration can naturally fit into this pattern.
2. Jeremiah’s Curse
“Cursed be the day on which I was born! The day when my mother bore me, let it not be blessed!” (Jer. 20:14)
Jeremiah, overwhelmed with sorrow and persecution, laments the day of his birth. But this lament actually reveals something about the normal view of birthdays. He prays that his birth-date would not be “blessed,” implying that under normal circumstances it would be a blessed and happy day, a time of rejoicing. In other words, you would only curse what is normally considered good.
3. Job celebrations
“His sons used to go and hold a feast in the house of each one on his day, and they would send and invite their three sisters to eat and drink with them.” (Job 1:4)
The phrase “on his day” is commonly understood by many interpreters as referring to each son’s particular birthday. This fits well with the pattern we see elsewhere in Scripture, especially when compared with Job 3:1:
“After this Job opened his mouth and cursed the day of his birth.”
Barnes’ Notes that “perhaps it refers only to their birthdays; see Job 3:1, where the word day is used to denote a birthday. In early times the birthday was observed with great solemnity and rejoicing.”
This shows that a person’s “day” can clearly mean the day of his birth. Taken together, these passages strongly suggest that Job’s sons may have been marking their birthdays with feasts—a family custom that Job does not condemn. Instead, he responds not by rebuking them, but by interceding for them just in case they sinned in their hearts (Job 1:5).
The concern is not the fact of feasting, but the spirit in which it is done.
4. The Birth of John & Jesus
The angel says to Zechariah regarding John and points ahead to Jesus:
“You will have joy and gladness, and many will rejoice at his birth.” (Luke 1:14)
If rejoicing at the birth of John is good and God-approved, how much more at the birth of Jesus? His birth reveals God’s attitude toward the arrival of a child, it is the birth of His own uniquely procreated human Son, Jesus.
“I bring you good news of great joy that will be for all the people. For unto you is born this day in the city of David a Savior, who is Christ the Lord.” (Luke 2:10–11)
Immediately after, “a multitude of the heavenly host” praises God:
“Glory to God in the highest, and on earth peace among those with whom he is pleased!” (Luke 2:13–14)
Heaven itself rejoices at the birth of Christ. The day of his birth is not treated as a neutral or irrelevant event. It is a cause of great joy and leads to worship, thanksgiving, and praise.
“When they saw the star, they rejoiced exceedingly with great joy. And going into the house they saw the child with Mary his mother, and they fell down and worshiped him.” (Matt. 2:10–11)
The wise men are not condemned for honoring the child’s birth; rather, their actions fulfill prophecy and reveal the right response to God’s saving work.
While our birthdays are obviously not on the same level as the Messiah’s, the pattern remains: the birth of a person—especially in God’s purposes—is a proper occasion for rejoicing, thanksgiving, and even gathering with gifts. Joy at someone’s birth is presented as natural, wholesome, and God-given.
Therefore, celebrating a birthday is not in itself sinful. Like any other human custom, it can be abused through pride and self-indulgence, or conflated with pagan practices, instead of being offered to God in thanksgiving and obedience.
When we use birthdays to remember our Creator and His Son, we are not merely “having a party”—we are glorifying the God who gave us life in the first place.
