This gradual growing up of the practice is in accordance with the whole spirit of the New Covenant, which has next to nothing to say about the externals of worship, and leaves the new life to shape itself. Judaism gave prescriptions and minute regulations; Christianity, the religion of the spirit, gives principles. The necessity, for the nourishment of the Divine life, of the religious observance of the day of rest is certainly not less now than at first. In the hurry and drive of our modern life with the world forcing itself on us at every moment, we cannot keep up the warmth of devotion unless we use this day, not merely for physical rest, and family enjoyment, but for worship. They who know their own slothfulness of spirit, and are in earnest in seeking after a deeper, fuller Christian life, will thankfully own, "the week were dark but for its light." I distrust the spirituality which professes that all life is a sabbath, and therefore holds itself absolved from special seasons of worship. If the stream of devout communion is to flow through all our days, there must be frequent reservoirs along the road, or it will be lost in the sand, like the rivers of higher Asia. It is a poor thing to say, keep the day as a day of worship because it is a commandment. Better to think of it as a great gift for the highest purposes; and not let it be merely a day of rest for jaded bodies, but make it one of refreshment for cumbered spirits, and rekindle the smouldering flame of devotion, by drawing near to Christ in public and in private. So shall we gather stores that may help us to go in the strength of that meat for some more marches on the dusty road of life. II. The Apostle passes on to his second peal of warning,--that against the teaching about angel mediators, which would rob the Colossian Christians of their prize,--and draws a rapid portrait of the teachers of whom they are to beware.
