From the Lesson for the 23rd Sunday of Pentecost (Phil 3:17-21; 4:1-3) – “Their end is ruin, their god is the belly, their glory is their shame, they mind the things of earth. But our citizenship is in heaven from which also we eagerly await a Savior, our Lord Jesus Christ, Who will refashion the body of our lowliness, conforming it to the body of His glory by exerting the power by which He is able also to subject all things to Himself.”
The World, material things, power, prestige, ego – they all come to nothing in the end. Their God is the belly – pleasure, comfort. Their glory is their shame – those things which they hold as dear now will be seen in the end to be empty. The problem is not the things of the earth, the problem is minding the things of Earth, because we are citizens of heaven. To be poor in spirit is the opposite of minding the things of the earth.
