Philippians 1:5

"For your fellowship in furtherance of the Gospel from the first day even until now." Great is that he here witnesseth of them, and very great, and what one might have witnessed of Apostles and Evangelists. Ye did not, because ye were entrusted with one city, he saith, care for that only, but ye leave nothing undone to be sharers of my labors, being everywhere at hand and working with me, and taking part in my preaching. It is not once, or the second, or third time, but always, from the time ye believed until now, ye have assumed the readiness of Apostles. Behold how those indeed that were in Rome turned away from him; for hear him saying, "This thou knowest, that all that are in Asia turned away from me." And again, "Demas forsook me": and "at my first defence no one took my part." But these, although absent, shared in his tribulations, both sending men to him, and ministering to him according to their ability, and leaving out nothing at all. And this ye do not now only, saith he, but always, in every way assisting me. So then it is a "fellowship in furtherance of the Gospel." For when one preacheth, and thou waitest on the preacher, thou sharest his crowns. Since even in the contests that are without, the crown is not only for him that striveth, but for the trainer, and the attendant, and all that help to prepare the athlete. For they that strengthen him, and recover him, may fairly participate in his victory. And in wars too, not only he that wins the prize of valor, but all they too that attend him, may fairly claim a share in the trophies, and partake of the glory, as having shared in his conflict by their attendance on him. For it availeth not a little to wait on saints, but very much. For it makes us sharers in the rewards that are laid up for them. Thus; suppose some one hath given up great possessions for God, continually devotes himself to God, practices great virtue, and even to words, and even to thoughts, and even in everything observes extreme strictness. It is open to thee too, even without showing such strictness, to have a share in the rewards that are laid up for him for these things. How? If thou aid him both in word and deed. If thou encourage him both by supplying his needs, and by doing him every possible service. For then the smoother of that rugged path will be thyself. So then if ye admire those in the deserts that have adopted the angelic life, those in the churches that practice the same virtues with them; if ye admire, and are grieved that ye are far behind them; ye may, in another way, share with them, by waiting on them, and aiding them. For indeed this too is of God's lovingkindness, to bring those that are less zealous, and are not able to undertake the hard and rugged and strict life, to bring, I say, even those, by another way, into the same rank with the others. And this Paul means by "fellowship." They give a share to us, he means, in carnal things, and we give a share to them in spiritual things. For if God for little and worthless things granteth the kingdom, His servants too, for little and material things, give a share in spiritual things: or rather it is He that giveth both the one and the other by means of them.
