I Can’t Believe He’s Not Butter:

“I wanted this song to be an encouragement
to young girls to keep waiting for their butter.
What I mean by butter is a guy who is truly devoted
to the Lord, to honoring God in their relationship and
someone who is her best friend. In a world of margarine,
wait for the real thing, your butter. There are guys out
there who are genuine servants of God.

What qualities should girls look for in a guy?
My dad always said, Wait for the man that most represents
Christ to you on this planet.That is a super-tall order,
but there are guys out there who are like that
— who treat their moms well, who open doors for young
women, who help elderly women with their bags and
who have a good relationship with their dad and/or who
are being mentored, and may even mentor other
people.”

This article offers some good suggestions on integrity and not just assuring yourself he is the right guy.
