I gave the following (solicited) advice to a brother in Christ yesterday about dating (summarized):
* Look for someone who reads God's word.
* When considering asking someone out, PRAY about it.
I told him the first suggestion, because that is what I'm praying for in a husband.
BOOK I : Psalms 1-41
1 Blessed is the man
who does not walk in the counsel of the wicked
or stand in the way of sinners
or sit in the seat of mockers.
2 But his delight is in the law of the LORD,
and on his law he meditates day and night.
3 He is like a tree planted by streams of water,
which yields its fruit in season
and whose leaf does not wither.
Whatever he does prospers.
4 Not so the wicked!
They are like chaff
that the wind blows away.
5 Therefore the wicked will not stand in the judgment,
nor sinners in the assembly of the righteous.
6 For the LORD watches over the way of the righteous,
but the way of the wicked will perish.
I mentioned the second suggestion, because talking to the LORD about it is just the wise thing to do! :)
