But to return to the text. The Epistle closes, as the Apostle's custom is, with a benediction: "The grace of our Lord Jesus Christ be with you all." Grace is pre-eminently a Pauline word; it is found alike in the salutations with which Paul addresses his churches, and in the benedictions with which he bids them farewell; it is the beginning and the end of his gospel; the element in which Christians live, and move, and have their being. He excludes no one from his blessing; not even those who had been walking disorderly, and setting at nought the tradition they had received from him; their need is the greatest of all. If we had imagination enough to bring vividly before us the condition of one of these early churches, we would see how much is involved in a blessing like this, and what sublime confidence it displays in the goodness and faithfulness of our Lord. The Thessalonians, a few months ago, had been heathens; they had known nothing of God and His Son; they were living still in the midst of a heathen population, under the pressure of heathen influences both on thought and conduct, beset by numberless temptations; and if they were mindful of the country from which they had come forth, not without opportunity to return. Paul would willingly have stayed with them to be their pastor and teacher, their guide and their defender, but his missionary calling made this impossible. After the merest introduction to the gospel, and to the new life to which it calls those who receive it, they had to be left to themselves. Who should keep them from falling? Who should open their eyes to understand the ideal which the Christian is summoned to work out in his life? Amid their many enemies, where could they look for a sufficient and ever-present ally? The Apostle answers these questions when he writes, "The grace of our Lord Jesus Christ be with you all." Although he has left them, they are not really alone. The free love of God, which visited them at first uncalled, will be with them still, to perfect the work it has begun. It will beset them behind and before; it will be a sun and a shield to them, a light and a defence. In all their temptations, in all their sufferings, in all their moral perplexities, in all their despondencies, it will be sufficient for them. There is not any kind of succour which a Christian needs which is not to be found in the grace of the Lord Jesus Christ.
