Today Jesus tells us we are "the light of the world." Isaiah challenges us share your bread with the hungry, shelter the oppressed and the homeless; clothe the naked when you see them, and do not turn your back on your own." These wise counsels from Isaiah and Jesus are two sides of the same coin. It is only when we feed the hungry and shelter the un-housed that our "light shall break forth like the dawn." And if the light of Christ in us is to be seen by anyone, they must see us serving the poor. There really is no other way that the Gospel is truly proclaimed to the ends of the earth.
God has a plan for each one of us; God also has a plan for all of us together. If we really believe that we are saved in Christ, that we are truly set free from sin and death, then we are compelled to share that good news. The best, dare I say, "the only" way for us to share that good news is by lifting up the poor. I really believe that if the Church set its priority on the transformation of the world in such a way that all the hungry have food and all the un-housed have shelter, that people would indeed "see (y)our good deeds and glorify (y)our heavenly Father."
Let's take some time to examine the structures of society that still make it very difficult for the poor to find a way out of poverty (e.g. early childhood development and really affordable housing); and let's devote more of our resources, actually most, to addressing the needs of the hungry and the un-housed in our community and throughout the world. We can do this if we set our hearts and minds to get it done; we can do this if we truly believe in Jesus Christ.
Behold the Lamb of God who takes away the sins of the world.
