She 'laboured much in the Lord,' or, as Jesus Christ said about the other woman who was blamed by the people that did not love enough to understand the blessedness of self-sacrifice, 'she had done what she could.' It was an apology for the form of Mary's service, but it was a stringent demand as to its amount. 'What she could'--not _half_ of what she could; not what she _conveniently_ could. That is the measure of acceptable service.
Then, still further, may we not learn from Persis the spring of all true Christian work? She 'laboured much in the Lord,' because she _was_ 'in Him,' and in union with Him there came to her power and desire to do things which, without that close fellowship, she neither would have desired nor been able to do. It is vain to try to whip up Christian people to forms of service by appealing to lower motives. There is only one motive that will last, and bring out from us all that is in us to do, and that is the appeal to our sense of union and communion with Jesus Christ, and the exhortation to live in Him, and then we shall work in Him. If you link the spindles in your mill, or the looms in your weaving-shed, with the engine, they will go. It is of no use to try to turn them by hand. You will only spoil the machinery, and it will be poor work that you will get off them.
So, dear brethren, be 'in the Lord.' That is the secret of service, and the closer we come to Him, and the more continuously, moment by moment, we realise our individual dependence upon Him, and our union with Him, the more will our lives effloresce and blossom into all manner of excellence and joyful service, and nothing else that Christian people are whipped up to do, from lower and more vulgar motives than that, will. It may be of a certain kind of inferior value, but it is far beneath the highest beauty of Christian service, nor will its issues reach the loftiest point of usefulness to which even our poor service may attain.
Persis seems to me to suggest, too, the safeguard of work. Ah, if she had not 'laboured in the Lord,' and been 'in the Lord' whilst she was labouring, she would very soon have stopped work. Our Christian work, however pure its motive when we begin it, has in itself the tendency to become mechanical, and to be done from lower motives than those from which it was begun. That is true about a man in my position. It is true about all of us, in our several ways of trying to serve our dear Lord and Master. Unless we make a conscience of continually renewing our communion with Him, and getting our feet once more firmly upon the rock, we shall certainly in our Christian work, having begun in the spirit, continue in the flesh, and before we know where we are, we shall be doing work from habit, because we did it yesterday at this hour, because people expect it of us, because A, B, or C does it, or for a hundred other reasons, all of which are but too familiar to us by experience. They are sure to slip in; they change the whole character of the work, and they harm the workers. The only way by which we can keep the garland fresh is by continually dipping it in the fountain. The only way by which we can keep our Christian work pure, useful, worthy of the Master, is by seeing to it that our work itself does not draw us away from our fellowship with Him. And the more we have to do, the more needful is it that we should listen to Christ's voice when He says to us, 'Come ye yourselves apart with Me into a solitary place, and there renew your communion with Me.'
