The BIBLE says the age difference between couples is

A search for “age differences in relationships” in the Bible returns no direct results. In Scripture, an individual’s age is rarely mentioned, a trend that holds true for married couples as well—aside from one exception, the Bible offers no account of the age gap between partners. The only pair whose ages are noted is Abraham and Sarah. When God promised Abraham that he and Sarah would become the ancestors of many nations, Abraham laughed in disbelief, asking, “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). This rare moment of numerical detail suggests that Abraham and Sarah were about ten years apart—noticeable, though not an extreme difference. No other biblical couples have their ages recorded in this way.

Another frequently discussed example is Boaz and Ruth. It’s often assumed that Boaz was significantly older than Ruth, based on Ruth 3:10, where Boaz remarks, “The Lord bless you, my daughter… You have not run after the younger men, whether rich or poor.” This comment has led some to speculate that Ruth purposefully sought out a more mature man, conforming to Jewish customs of the time. According to later Jewish tradition in the Mishnah (Ruth Rabbah 7:4; Ruth Zuta 4:13), Boaz was thought to be 80 and Ruth 40—though the Bible itself does not confirm any specific ages.

Similarly, many assume that Joseph must have been considerably older than Mary, but there is absolutely no biblical evidence to support this view. The silence of Scripture on age differences suggests that such details are not of primary concern to God. While age may hold practical significance in a marriage, other factors—such as salvation, spiritual maturity, and compatibility—carry far greater weight. As individuals grow older, the importance of an age gap diminishes; a significant disparity between a 40-year-old and an 18-year-old may raise eyebrows, but an 82-year-old marrying a 60-year-old is generally seen as far less remarkable.

Ultimately, the Bible emphasizes that the person one marries should be of the opposite gender (Genesis 2:21–25), a believer in Christ (2 Corinthians 6:14), and chosen for the right reasons—far removed from motives like lust or greed. While age differences should be considered wisely, especially when they are substantial (James 1:5), Scripture does not regard them as a moral or spiritual issue.
