The contrast between the names of these two Roman ladies and the characterisation of their 'labour in the Lord' may suggest to us the most formidable foe of Christian earnestness. Their names, as we have already noticed, point to a state of society in which the parents ideal for their daughters was dainty luxuriousness and a withdrawal from the rough and tumble of common life; but these two women, magnetised by the love of Jesus, had turned their backs on the parental ideal, and had cast themselves earnestly into a life of toil. That ideal was never more formidably antagonistic to the vigour of Christian life than it is to-day. Rome, in Paul's time, was not more completely honeycombed with worldliness than England is to-day; and the English churches are not far behind the English 'world' in their paralysing love of luxury and self-indulgence. In all ages, earnest Christians have had to take up the same vehement remonstrance against the tendency of the average Christian to let his religious life be weakened by the love of the world and the things of the world. The protests against growing luxury have been a commonplace in all ages of the Church; but, surely, there has never been a time when it has reached a more senseless, sinful, and destroying height than in our day. The rapid growth of wealth, with no capacity of using it nobly, which modern commerce has brought, has immensely influenced all our churches for evil. It is so hard for us, aggregated in great cities, to live our own lives, and the example of our class has such immense power over us that it is very hard to pursue the path of 'plain living and high thinking' in communities, all classes of which are more and more yielding to the temptation to ostentation, so-called comfort, and extravagant expenditure; and that this is a danger--we are tempted to say _the_ danger--to the purity, loftiness, and vigour of religious life among us, he must be blind who cannot see, and he must be strangely ignorant of his own life who cannot feel that it is the danger for him. I believe that for one professing Christian whose earnestness is lost by reason of intellectual doubts, or by some grave sin, there are a hundred from whom it simply oozes away unnoticed, like wind out of a bladder, so that what was once round and full becomes limp and flaccid. If Demas begins with loving the present world, it will not be long before he finds a reason for departing from Paul.
