Barclay's short study is filled with many rich and meaningful observations. It's impossible to choose among them without also saying that you must read the whole thing. Nevertheless, there are some things that all might benefit from. And for those Christians among us whose inclination is to deride or demean or otherwise detract from other Christians, Barclay has this observation:
from Barclay's Commentary on the Letter to the Philippians
There is a lesson for us here. Paul knew nothing of personal jealousy or of personal resentment. So long as Jesus Christ was preached, he did not care who received the credit and the prestige. He did not care what other preachers said about him, or how unfriendly they were to him, or how contemptuous they were of him, or how they tried to steal a march upon him. All that mattered was that Christ was preached. All too often we resent it when someone else gains a prominence or a credit which we do not. All too often we regard a man as an enemy because he has expressed some criticism of us or of our methods. All too often we think a man can do no good because he does not do thing in our way. . . . Paul is the great example. He lifted the matter beyond all personalities; all that mattered was that Christ was preached.
