And so, says Paul, you Christian men and women belong to a joyous realm, a realm of light and knowledge, a realm of purity and righteousness. You are children of the light; a glad condition which involves many glad and noble issues. Children of the light should be brave, children of the light should not be afraid of the light, children of the light should be cheerful, children of the light should be buoyant, children of the light should be transparent, children of the light should be hopeful, children of the light should be pure, and children of the light should walk in this darkened world, bearing their radiance with them; and making things, else unseen, visible to many a dim eye.
But while these emblems of cheerfulness, hope, purity, and illumination are gathered together in that grand name--'Ye are the children of the day,' there is one direction especially in which the Apostle thinks that that consideration ought to tell, and that is the direction of self-restraint. '_Noblesse oblige!_'--the aristocracy are bound to do nothing low or dishonourable. The children of the light are not to stain their hands with anything foul. Chambering and wantonness, slumber and drunkenness, the indulgence in the appetites of the flesh,--all that may be fitting for the night, it is clean incongruous with the day.
Well, if you want that turned into pedestrian prose--which is no more clear, but a little less emotional--it is just this: You Christian men and women belong--if you are Christians--to another state of things from that which is lying round about you; and, therefore, you ought to live in rigid abstinence from these things that are round about you.
That is plain enough surely, nor do I suppose that I need to dwell on that thought at any length. We belong to another order of things, says Paul; we carry a day with us in the midst of the night. What follows from that? Do not let us pursue the wandering lights and treacherous will-o'-the-wisps that lure men into bottomless bogs where they are lost. If we have light in our dwellings whilst Egypt lies in darkness, let it teach us to eat our meat with our loins girded, and our staves in our hands, not without bitter herbs, and ready to go forth into the wilderness. You do not belong to the world in which you live, if you are Christian men and women; you are only camped here. Your purposes, thoughts, hopes, aspirations, treasures, desires, delights, go up higher. And so, if you are children of the day, be self-restrained in your dealings with the darkness.
III. And, last of all, my text points out for us a method by which this great precept may be fulfilled:--'Putting on the breastplate of faith and love, and for an helmet the hope of salvation.'
That, of course, is the first rough draft occurring in Paul's earliest Epistle, of an image which recurs at intervals, and in more or less expanded form in other of his letters, and is so splendidly worked out in detail in the grand picture of the Christian armour in the Epistle to the Ephesians.
I need not do more than just remind you of the difference between that finished picture and this outline sketch. Here we have only defensive and not offensive armour, here the Christian graces are somewhat differently allocated to the different parts of the armour. Here we have only the great triad of Christian graces, so familiar on our lips--faith, hope, charity. Here we have faith and love in the closest possible juxtaposition, and hope somewhat more apart. The breastplate, like some of the ancient hauberks, made of steel and gold, is framed and forged out of faith and love blended together, and faith and love are more closely identified in fact than faith and hope, or than love and hope. For faith and love have the same object--and are all but contemporaneous. Wherever a man lays hold of Jesus Christ by faith, there cannot but spring up in his heart love to Christ; and there is no love without faith. So that we may almost say that faith and love are but the two throws of the shuttle, the one in the one direction and the other in the other; whereas hope comes somewhat later in a somewhat remoter connection with faith, and has a somewhat different object from these other two. Therefore it is here slightly separated from its sister graces. Faith, love, hope--these three form the defensive armour that guard the soul; and these three make self-control possible. Like a diver in his dress, who is let down to the bottom of the wild, far-weltering ocean, a man whose heart is girt by faith and charity, and whose head is covered with the helmet of hope, may be dropped down into the wildest sea of temptation and of worldliness, and yet will walk dry and unharmed through the midst of its depths, and breathe air that comes from a world above the restless surges.
