This [Philippians 4:6,7] is undoubtedly one of the noblest, greatest and most comforting statements . . . in any extant literature . . . there is nothing that has greater comfort for God's people than these two verses.... Here in these verses he goes on to consider another factor that is perhaps more problematical than any of the others which tend to rob us of the joy of the Lord, and that is what we may well describe as the tyranny of circumstances, or the things that happen to us. How many they are, and how often do they come! ... all the New Testament epistles face this particular problem, and were designed to help the first Christians to overcome the tyranny of circumstances. They lived in a very difficult world and had to suffer and to endure a great deal; and these men called of God wrote their letters in order to show them how to overcome these things. It is the great theme of the New Testament; but you find it also in the Old Testament. Take the third and fourth Psalms, for instance. How perfectly they put it all. The great problem in life is, in a sense, how to lay oneself down to rest and to sleep. 'I laid me down and slept', said the Psalmist. Anybody can lie down, but the question is can you sleep? The Psalmist describes himself surrounded by enemies and by difficulties and trials, and his mighty testimony is that in spite of that, because of his trust in the Lord, he both laid him down and slept, and he awaked safe and sound in the morning. Why? Because the Lord was with him and looking after him.
