The ancient world was honeycombed with rents and schisms, scarcely masked by political union. In the midst of a world of selfishness this new faith started up, and by some magic knit warring nationalities and hostile classes and wide diversities of culture and position into a strange whole, transcending all limits of race and language. The conception of brotherhood was new, and the realisation of it in Christian love was still more astonishing. The world wondered; but to the Christians the new affection was, we might almost say, instinctive, so naturally and spontaneously did it fill their hearts.
Paul's graceful way of enjoining it here is no mere pretty compliment. The Thessalonians did not need to be bidden to love the brethren, for such love was a part of their new life, and breathed into their hearts by God Himself. They were drawn together by common relation to Jesus, and driven together by common alienation from the world. Occasions of divergence had not yet risen. The world had not yet taken on a varnish of Christianity. The new bond was still strong in its newness: So, short as had been the time since Paul landed at Neapolis, the golden chain of love bound all the Macedonian Christians together, and all that Paul had to exhort was the strengthening of its links and their tightening.
That fair picture faded soon, but it still remains true that the deeper our love to Jesus, the warmer will be our love to all His lovers. The morning glow may not come back to the prosaic noonday, but love to the brethren remains as an indispensable token of the Christian life. Let us try ourselves thereby.
