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. But the Apostle, in the immediately following words, goes on to pass beyond the bounds of his metaphor, and with complete indifference to the charge of mixing figures, speaks of the building as growing. That thought leads us into a higher region than that of effort. The process by which a great forest tree thickens its boles, expands the sweep of its branches and lifts them nearer the heavens, is very different from that by which a building rises slowly and toilsomely and with manifest incompleteness all the time, until the flag flies on the roof-tree. And if we had not this nobler thought of a possible advance by the increasing circulation within us of a mysterious life, there would be little gospel in a word which only enjoined effort as the condition of moral progress, and there would be little to choose between Paul and Plato. He goes on immediately to bring out more fully what he means by the growth of the building, when he says that if Christians are in Christ, they are 'built up for an habitation of God in the Spirit.' Union with Christ, and a consequent life in the Spirit, are sure to result in the growth of the individual soul and of the collective community. That divine Spirit dwells in and works through every believing soul, and while it is possible to grieve and to quench It, to resist and even to neutralise Its workings, these are the true sources of all our growth in grace and knowledge. The process of building may be and will be slow. Sometimes lurking enemies will pull down in a night what we have laboured at for many days. Often our hands will be slack and our hearts will droop. We shall often be tempted to think that our progress is so slow that it is doubtful if we have ever been on the
