What Kind Of Prayer

What kind of prayer…

And I pray this, that your love may abound even more and more in knowledge and every kind of insight so that you can decide what is best, and thus be sincere and blameless for the day of Christ, filled with the fruit of righteousness that comes through Jesus Christ to the glory and praise of God.  –Philippians 1:9-11

I prayed this prayer for a couple once.  I had no words of thanks for them at the time so it was what I could give them oh so many years ago.  I remember this with great affection several times each year as I read the book of Philippians.  As they come to mind, I love to pray for them again.  Prayers from the Bible always seem more eloquent than mine.  Today, this couple is my special prayer request.  What is your favorite prayer in the Bible?
