I found this Lenten devotional from priest and spiritual writer Henri Nouwen especially meaningful.  I hope you do, too.

They devoted themselves to the apostles' teaching and fellowship, to the breaking of bread and the prayers.  Acts 2:42

To pray for one another is, first of all, to acknowledge, in the presence of God, that we belong to each other as children of the same God.  Without this acknowledgment of human solidarity, what we do for one another does not flow from who we truly are.  We are brothers and sisters, not competitors or rivals.  We are children of one God, not partisans of different gods.  

To pray, that is, to listen to the voice of the One who calls us the "beloved", is to learn that that voice excludes no one.  Where I dwell, God dwells with me, and where God dwells with me, I find all my sisters and brothers.  And so intimacy with God and solidarity with all people are two aspects of dwelling in the present moment that can never be separated.
