16For if I preach the gospel, that gives me no ground for boasting. For necessity is laid upon me. Woe to me if I do not preach the gospel! 17For if I do this of my own will, I have a reward; but if not of my own will, I am entrusted with a commission. 18What then is my reward? Just this: that in my preaching I may make the gospel free of charge, not making full use of my right in the gospel. 19For though I am free from all men, I have made myself a slave to all, that I might win the more. 22To the weak I became weak, that I might win the weak. I have become all things to all men, that I might by all means save some. 23I do it all for the sake of the gospel, that I may share in its blessings. 24Do you not know that in a race all the runners compete, but only one receives the prize? So run that you may obtain it. 25Every athlete exercises self-control in all things. They do it to receive a perishable wreath, but we an imperishable. 26Well, I do not run aimlessly, I do not box as one beating the air; 27but I pommel my body and subdue it, lest after preaching to others I myself should be disqualified.
Psalms 84:3-6, 12
2My soul longs, yea, faints for the courts of the LORD; my heart and flesh sing for joy to the living God. 3Even the sparrow finds a home, and the swallow a nest for herself, where she may lay her young, at thy altars, O LORD of hosts, my King and my God. 4Blessed are those who dwell in thy house, ever singing thy praise! [Selah] 5Blessed are the men whose strength is in thee, in whose heart are the highways to Zion. 11For the LORD God is a sun and shield; he bestows favor and honor. No good thing does the LORD withhold from those who walk uprightly.
39He also told them a parable: "Can a blind man lead a blind man? Will they not both fall into a pit? 40A disciple is not above his teacher, but every one when he is fully taught will be like his teacher. 41Why do you see the speck that is in your brother's eye, but do not notice the log that is in your own eye? 42Or how can you say to your brother, `Brother, let me take out the speck that is in your eye,' when you yourself do not see the log that is in your own eye? You hypocrite, first take the log out of your own eye, and then you will see clearly to take out the speck that is in your brother's eye.
