Love of God and Love of Neighbor

From God is Love by Pope Benedict XVI:

Seeing with the eyes of Christ, I can give to others much more than their outward necessities; I can give them the look of love which they crave. Here we see the necessary interplay between love of God and love of neighbor which the First Letter of John speaks of with such insistence. If I have no contact whatsoever with God in my life, then I cannot see in the other anything more than the other, and I am incapable of seeing in him the image of God. But if in my life I fail completely to heed others, solely out of a desire to be "devout" and to perform my "religious duties," then my relationship with God will also grow arid. It becomes merely "proper," but loveless. Only my readiness to encounter my neighbor and to show him love makes me sensitive to God as well. Only if I serve my neighbor can my eyes be opened to what God does for me and how much he loves me. The saints - consider the example of Blessed Teresa of Calcutta - constantly renewed their capacity for love of neighbor from their encounter with the Eucharistic Lord, and conversely this encounter acquired its realism andd depth in their service to others. Love of God and love of neighbor are thus inseparable, they form a single commandment. But both live from the love of God who has loved us first.
