Bahnsen8 stated it well, family is one of GOD's greatest plans. Singleness is a time to be used to focus on GOD and His will. Is the single person, male or female, pleasing GOD? The over 30 yr old man Lady Abigail mentioned, his he living for the LORD as he waits? Joseph was single until after he was promoted to second in charge of Egypt, all the while doing the will of GOD, some say he was in his 30's when he married. Joe listed several good Biblical references. The Proverbs is full of references to marriage, as well is The Song of Solomon. Paul paints a written picture of the church and marriage in Ephesians 5. Paul also shows that married people will focus more on each other compare to the single person who can focus on GOD.
