Meditate: (1 John 2:9-11)
9. The one who says he is in the Light and yet hates his brother is in the darkness until now.
10 The one who loves his brother abides in the Light and there is no cause for stumbling in him.
11 But the one who hates his brother is in the darkness and walks in the darkness, and does not know where he is going because the darkness has blinded his eyes.
Prayer: Open our hands and mouth as you open our hearts and our mind, and remember today the National Allience to End Homelessness, and all the activist who work diligently to bring justice to all in need of some place to call home.
