In the first chapter of Philippians, Paul prays several times for his friends.  In particular, verses 9-11 asks for them that

• Your love may abound more and more
• Your love will be filled with knowledge and all discernment
• You may be able to approve what is excellent
• You may be pure and blameless for the day of Christ
• You may be filled with the fruit of righteousness that comes from Christ
• You may glorify and praise God

Not bad for a one-sentence prayer!
