Charles H. Spurgeon on Psalms 119:6

All thy commandments. There is the same reason for obedience to one command as another, God's authority, who is the Lawgiver (James 2:11); and therefore when men choose one duty and overlook others, they do not so much obey the will of God, as gratify their own humours and fancies, pleasing Him only so far as they can please themselves too; and this is not reasonable; we never yield him a "reasonable service, "but when it is universal. Edward Veal (1632-1708), in "The Morning Exercises."
