If we are serious about loving God, we must begin with people, all people. And especially we must learn to love those that the world generally discards.
Every day you and I walk through God's shop. Every day we brush up against objects of incalculable worth to Him. People. Every one of them carries a price tag, if only we could see it.
If you want to do the work of God, pay attention to people. Notice them. Especially the people nobody else notices.
When we live in the love of God, we begin to pay attention to people the way God pays attention to us.
