Christian singles and pick up lines

Yesterday returning from a seminar I met a man who stopped me to say "lady you can make a good wife" I just smiled and went my way. But it got me thinking,

How does a Christian single approach another single for a date?

what are some pick-up statements that Christian singles can safely use?

By the way inspired by @seoulsearch I am gathering the singles of my church for a retreat during the summer holidays. I wonder what we will be teaching, please any ideas?

You can go with the Anakin Skywalker one,
"Are you an angel?"

That might work for sure.

Be sure you have a good strong stomach before you click on that. Some of them can be very, extremely cheesy.

Ok....
I got a "different" view in that you should NEVER NEVER NEVER date anyone you don't know a LOT about.

IOW.....you should date friends instead of acquaintances. So be friendly, generous, kind, and genuine to LOTS of people....
It really doesn't cost you much but time developing relationships with everyone. Get to know those who have a thin line of attachment in your world. (Attend your church, deliver packages, delivers water, sweeps halls, repairs equipment or whatever. Asking questions about them....

But I love pick-up lines....they are a fun way to flirt without doing anything harmful or wrong. Everyone smiles at the pickup lines I use... they are NOT intended for actually picking someone up.
Dunno anything about that.
