I. The process of building.
In the previous clauses the Apostle has represented the condition of the Ephesian Christians before their Christianity as being that of strangers and foreigners, lacking the rights of citizenship anywhere, a mob rather than in any sense a society. They had been like a confused heap of stones flung fortuitously together; they had become fellow-citizens with the saints. The stones had been piled up into an orderly building. He is not ignoring the facts of national, political, or civic relationships which existed independent of the new unity realised in a common faith. These relationships could not be ignored by one who had had Paul's experience of their formidable character as antagonists of him and of his message, but they seemed to him, in contrast with the still deeper and far more perfect union, which was being brought about in Christ, of men of all nationalities and belonging to mutually hostile races, to be little better than the fortuitous union of a pile of stones huddled together on the roadside. Measured against the architecture of the Church, as Paul saw it in his lofty idealism, the aggregations of men in the world do not deserve the name of buildings. His point of view is the exact opposite of that which is common around us, and which, alas! finds but too much support in the present aspects of the so-called churches of this day.
It is to be observed that in our text these stones are, in accordance with the propriety of the metaphor, regarded as _being_ built, that is, as in some sense the subjects of a force brought to bear upon them, which results in their being laid together in orderly fashion and according to a plan, but it is not to be forgotten that, according to the teaching, not of this epistle alone, but of all Paul's letters, the living stones are active in the work of building, as well as beings subject to an influence. In another place of the New Testament we read the exhortation to 'build up yourselves on your most holy faith,' and the means of discharging that duty are set forth in the words which follow it; as being 'Praying in the Holy Spirit, keeping yourselves in the love of God, and looking for the mercy of our Lord Jesus Christ.'
Throughout the Pauline letters we have frequent references to _edifying_, a phrase which has been so vulgarised by much handling that its great meaning has been all but lost, but which still, rightly understood, presents the Christian life as one continuous effort after developing Christian character. Taking into view the whole of the apostolic references to this continuous process of building, we cannot but recognise that it all begins with the act of faith which brings men into immediate contact and vital union with Jesus Christ, and which is, if anything that a man does is, the act of his very inmost self passing out of its own isolation and resting itself on Jesus. It is by the vital and individual act of faith that any soul escapes from the dreary isolation of being a stranger and a foreigner, wandering, homeless and solitary, and finds through Jesus fellowship, an elder Brother, a Father, and a home populous with many brethren. But whilst faith is the condition of beginning the Christian life, which is the only real life, that life has to be continued and developed towards perfection by continuous effort. 'Tis a life-long toil till the lump be leavened.'
One of the passages already referred to varies the metaphor of building, in so far as it seems to represent 'your most holy faith' as the foundation, and may be an instance of the doubtful New Testament usage of 'faith,' as meaning the believed Gospel, rather than the personal act of believing. But however that may be, context of the words clearly suggests the practical duties by which the Christian life is preserved and strengthened. They who build up themselves do so, mainly, by keeping themselves in the love of God with watchful oversight and continual preparedness for struggle against all foes who would drag them from that safe fortress, and subsidiarily, by like continuity in prayer, and in fixing their meek hope on the mercy of our Lord Jesus Christ unto eternal life. If Christian character is ever to be made more Christian, it must be by a firmer grasp and a more vivid realisation of Christ and His truth. The more we feel ourselves to be lapped in the love of God, the more shall we be builded up on our most holy faith. There is no mystery about the means of Christian progress. That which, at the beginning, made a man a Christian shapes his whole future course; the measure of our faith is the measure of our advance.
