There is no concrete answer to this question in the Bible, but perhaps there are principles that will apply.  Speaking of the lady and her desire to marry, we read in 1 Corinthians 7:39, “…she is at liberty to be married to whom she will; ONLY IN THE LORD.”  This is such an important element in choosing a spouse.  We should seek the Lord’s guidance to lead us to the right one to marry.  Even after we have found that person, we should be in constant prayer for the Lord to affirm to our hearts that this is His will that we marry.  In fact, the couple should be in constant prayer together to make sure it is the Lord’s will for them to marry.  Not only will the Lord lead us as to WHO we should marry, He will also lead us as to WHEN we should marry.  Marriage is a lifelong commitment and should not be entered into lightly.  In fact, it should be that ONLY when the couple is convinced that the Lord would have them to be married, that they should begin asking the Lord about when to get married.

Different cultures in different nations will probably dictate as to what age is appropriate to marry.  I thought it might be interesting to look at the average age for marriage in a few different countries.

USA – 28

Egypt – 31

Kenya – 22

Niger – 19

Bangladesh – 20

Denmark – 33

It is true that in our culture today, we marry later than in historical times.  However, we must fall back upon reliance upon the Lord to determine WHO and WHEN to marry. 

In Mark, chapter 5, a man named Jairus approached the Lord and asked Him to heal his daughter.  Before the Lord could reach his house, his daughter had died.  The Lord, in His graciousness and power, decided to raise her from the dead.  Let’s consider what we read in Mark 5:41-42, “Taking the child by the hand, He said to her, “Talitha kum!” (which translated means, “LITTLE GIRL, I say to you, get up!”). Immediately the girl got up and began to walk, for she was TWELVE YEARS OLD. And immediately they were completely astounded.”  (NASB).  We see that the Lord referred to this twelve-year-old girl as a LITTLE GIRL.  This should show us that at her age, she was still considered a child and it would not be acceptable to marry someone at this age.  One purpose in marriage is to procreate.  One who is too young cannot bear children and thus are too young to marry.

I assume by your question that you are interested in marrying someone.  I encourage you (and your partner) to pray together and allow the Lord to lead you.  We read in Mark 10:7-9, “For this cause shall a man leave his father and mother, and cleave to his wife; And they twain shall be one flesh: so then they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.”  The couple must be old enough and capable enough to leave their parents’ homes and establish their own home.  This means the man must be old enough to work to provide for his home.  The woman must be old enough to fulfill her role in the home.  The Lord intends for marriage to be permanent.  As we just read, “What therefore God hath joined together, let not man put asunder.”  Before entering into a marriage relationship, both must have the maturity and godliness to realize that this is a binding commitment which will last for the rest of their lives.  I encourage both of you to seek the Lord’s guidance and do not move forward until you both are convinced that this is the Lord’s will and his timing.  (423.4)
