of a company of soldiers, roused by the morning bugle, casting off their night-gear because the day is beginning to dawn, and bracing on the armour that sparkles in the light of the rising sun.  ‘That,’ says Paul, ’is what you Christian people ought to be.  Can you not hear the notes of the reveille?  The night is far spent; the day is at hand; therefore let us put off the works of darkness—­the night-gear that was fit for those hours of slumber.  Toss it away, and put on the armour that belongs to the day.’

Now, I am not going to ask or try to answer the question of how far this Apostolic exhortation is based upon the Apostle’s expectation that the world was drawing near its end.  That does not matter at all for us at present, for the fact which he expresses as the foundation of this exhortation is true about us all, and about our position in the midst of these fleeting shadows round us.  We are hastening to the dawning of the true day.  And so let me try to emphasise the exhortation here, old and threadbare and commonplace as it is, because we all need it, at whatever point of life’s journey we have arrived.

Now, the first thing that strikes me is that the garb for the man expectant of the day is armour.

We might have anticipated something very different in accordance with the thoughts that Paul’s imagery here suggests, about the difference between the night which is so swiftly passing, and is full of enemies and dangers, and the day which is going to dawn, and is full of light and peace and joy.  We might have expected that he would have said, ‘Let us put on the festal robes.’  But no!  ’The night is far spent; the day is at hand.’  But the dress that befits the expectant of the day is not yet the robe of the feast, but it is ‘the armour’ which, put into plain words, means just this, that there is fighting, always fighting, to be done.  If you are ever to belong to the day, you have to equip yourselves now with armour and weapons.  I do not need to dwell upon that, but I do wish to insist upon this fact, that after all that may be truly said about growth in grace, and the peaceful approximation towards perfection in the Christian character, we cannot dispense with the other element in progress, and that is fighting.  We have to struggle for every step. Growth is not enough to define completely the process by which men become conformed to the image of the Father, and are ’made meet to be partakers of the inheritance of the saints in light.’  Growth does express part of it, but only a part.  Conflict is needed to come in, before you have the whole aspect of Christian progress before your minds.  For there will always be antagonism without and traitors within.  There will always be recalcitrant horses that need to be whipped up, and jibbing horses that need to be dragged forward, and shying ones that need to be violently coerced and kept in the traces.  Conflict is the law, because of the enemies, and because of the conspiracy between the weakness within and the things without that appeal to it.
