I agree with Kate Wolf's "Give Yourself to Love" but would also suggest "All That Is" by Garnet Rogers. It has a great melody, a killer chorus and heartfelt lyrics. It is in the DT but here it is for those too lazy to look it up.

All that is
(Garnet Rogers)

Who can tell when in love you'll finally fall?
Some live in vain and never love at all.
But as lightning strikes or as a small insistent voice,
If we are blessed, we will hear and heed the call.

(Chorus:) Give your love and never count the cost.
Lose your heart and never call it lost.
May your love be a shelter to the ending of your days.
Love is all that is, and all that ever was.

May your love grow strong and always kind.
May your hearts grow forever more entwined.
In the brightest day or in the stillness of the night,
May it be each other's hand you seek and find.

Never more to be alone,
Ever closer you have grown.
Forever now may no distance come between,
And in each other's loving hearts you find a home.
