The reading is from St. Paul's Second Letter to the Corinthians 9:12-15; 10:1-7

Brethren, the rendering of this service not only supplies the wants of the saints but also overflows in many thanksgivings to God. Under the test of this service, you will glorify God by your obedience in acknowledging the gospel of Christ, and by the generosity of your contribution for them and for all others; while they long for you and pray for you, because of the surpassing grace of God in you. Thanks be to God for his inexpressible gift!

I, Paul, myself entreat you, by the meekness and gentleness of Christ - I who am humble when face to face with you, but bold to you when I am away! - I beg of you that when I am present I may not have to show boldness with such confidence as I count on showing against some who suspect us of acting in worldly fashion. For though we live in the world we are not carrying on a worldly war, for the weapons of our warfare are not worldly but have divine power to destroy strongholds. We destroy arguments and every proud obstacle to the knowledge of God, and take every thought captive to obey Christ, being ready to punish every disobedience, when your obedience is complete.

Look at what is before your eyes. If any one is confident that he is Christ's, let him remind himself that as he is Christ's, so are we.
