For the record, I absolutely do not subscribe to the "God would rather we all stay single and unmarried" line of thinking. This, in my opinion, is the slogan of the bitterly single. Or bitterly married, for that matter. Romantic love and marriage are absolutely celebrated in Scripture (Song of Solomon, anyone?), our relationship with Christ itself is painted as a bride and groom, not to mention that without Christian marriage, Christian families would cease to procreate and raise children (which is also praised in Scripture - Psalm 127). Pauls' opinions in the Bible are given as that - his opinions. As with all Scripture, it is God-breathed, and it has value, but singleness is not a command, nor is it "what God would prefer for all Christians".
Just my two cents.
