I found this lovely prayer at a blog called Kingdom People. There is no attribution so I assume it is by blog author Trevin Wax, a Baptist pastor in Tennessee. I love it when I find Baptists who “get” Advent!
Father in heaven,
our hearts desire the warmth of your love
and our minds are searching for the light of your Word.
Increase our longing for Christ our Savior
and give us the strength to grow in love,
that the dawn of his coming
may find us rejoicing in his presence
and welcoming the light of his truth.
We ask this in the name of Jesus the Lord.
You can find many more excellent prayers at this site as well.
