I'm on another board where quite a number of couples (at least, say, 7 that I know of, probably considerably more) have met. Quite a number of those relationships have been intercontinental: Australian-UK, UK-US and US-Aus.
Maybe I have the wrong impression, but there doesn't seem to be a large number of young single women on the PB.
God can certainly do whatever He wants and that includes putting whomever He wants together.
My wife and I were 900 miles apart and I never thought it was possible but God worked out all the details and today we are married and have several ministries which we do together.
