Paul here gives a precise standard, or 'measure' as he calls it, according to which we are to estimate ourselves. 'Faith' is the measure of our gifts, and is itself a gift from God. The strength of a Christian man's faith determines his whole Christian character. Faith is trust, the attitude of receptivity. There are in it a consciousness of need, a yearning desire and a confidence of expectation. It is the open empty hand held up with the assurance that it will be filled; it is the empty pitcher let down into the well with the assurance that it will be drawn up filled. It is the precise opposite of the self-dependent isolation which shuts us out from God. The law of the Christian life is ever, 'according to your faith be it unto you'; 'believe that ye receive and ye have them.' So then the more faith a man exercises the more of God and Christ he has. It is the measure of our capacity, hence there may be indefinite increase in the gifts which God bestows on faithful souls. Each of us will have as much as he desires and is capable of containing. The walls of the heart are elastic, and desire expands them. The grace given by faith works in the line of its possessor's natural faculties; but these are supernaturally reinforced and strengthened while, at the same time, they are curbed and controlled, by the divine gift, and the natural gifts thus dealt with become what Paul calls _charisms_. The whole nature of a Christian should be ennobled, elevated, made more delicate and intense, when the 'Spirit of life that is in Christ Jesus' abides in and inspires it. Just as a sunless landscape is smitten into sudden beauty by a burst of sunshine which heightens the colouring of the flowers on the river's bank, and is flashed back from every silvery ripple on the stream, so the faith which brings the life of Christ into the life of the Christian makes him more of a man than he was before. So, there will be infinite variety in the resulting characters. It is the same force in various forms that rolls in the thunder or gleams in the dewdrops, that paints the butterfly's feathers or flashes in a star. All individual idiosyncrasies should be developed in the Christian Church, and will be when its members yield themselves fully to the indwelling Spirit, and can truly declare that the lives which they live in the flesh they live by the faith of the Son of God.
