Charles H. Spurgeon on Psalms 103:20

Angels, that excel it, strength, that do his commandments. The chief excellence of the angels, the main cause of their strength and power, and of their immense superiority to mankind, is that which is set forth in the following words of the text. After the Psalmist has described the angels as excelling in strength, he adds that they do God's commandments, hearkening to the voice of his word. For this is the only living source of lasting strength and power. They who do the will of God faithfully and obediently, have God for them; and then what can be against them? Then work itself strengthens them, and is like a tide bearing them onward; because it is his work. They on the other hand who run counter to the will of God, have God against them; and then what can be for them? Can a man push back the sea? can he lay hold on the sun, and drag him out of his course? Then may he hope to be strong, when he is fighting against the will of God. . . . Hence we see the falsehood of that maxim, so common on the lips of those who plume themselves upon their mastery in the wisdom of this world —that Might is Right, —a maxim which exactly inverts the truth, and whereby the Prince of darkness is ever setting himself up against the Lord of heaven. The true principle, which is inverted and perverted in this falsehood, —the principle which ought to be written up in the councilchambers of princes and on the walls of senate-houses, —the principle which explains the secret of the strength of the angels, and indeed of all true strength, that is in accordance with the will of God, —may be stated in the selfsame words, if we only invert their order, Right is Might. Julius Charles Hare, 1849.
