Age difference in relationships is a common topic of discussion in modern society. Whether it’s concerns about compatibility, maturity, or cultural norms, people often ask: What is the biblical view of age differences between spouses?

When we examine the Bible, we find that age difference in marriage is not presented as a moral or spiritual concern. In fact, Scripture rarely focuses on the ages of couples or emphasizes age as a deciding factor in godly unions. Instead, the Bible prioritizes values such as faith, character, and spiritual compatibility.

Let’s explore what Scripture says—and doesn’t say—about age differences in marriage.

Biblical Examples: Abraham and Sarah
One of the few couples in the Bible whose ages are both mentioned is Abraham and Sarah. According to Genesis 17:17, when God promised Abraham a son through Sarah, Abraham was 100 years old and Sarah was 90, indicating a 10-year age difference.

“Abraham fell facedown; he laughed and said to himself, ‘Will a son be born to a man a hundred years old? Will Sarah bear a child at the age of ninety?’” — Genesis 17:17 (NIV)

This example shows that while the Bible acknowledges their age gap, it does not present it as problematic or spiritually inappropriate. Instead, the focus is on God’s covenant and the miraculous birth of Isaac.

What About Mary and Joseph?
Some traditions suggest that Joseph may have been older than Mary, but once again, the Bible does not give specific ages. In the Gospels, the emphasis is placed on Joseph’s righteousness and his obedience to God’s instructions (see Matthew 1:19–24), not on any age disparity.

Since Scripture is silent on their respective ages, making assumptions about age gaps between Mary and Joseph falls into the realm of extra-biblical speculation.
