"Stablished in your faith, even as ye were taught." This is apparently simply a more definite way of putting substantially the same thoughts as in the former clauses. Possibly the meaning is "stablished by faith," the Colossians' faith being the instrument of their establishment. But the Revised Version is probably right in its rendering, "stablished in," or as to, "your faith." Their faith, as Paul had just been saying, was stedfast, but it needed yet increased firmness. And this exhortation, as it were, translates the previous ones into more homely language, that if any man stumbled at the mysticism of the thoughts there, he might grasp the plain practicalness here. If we are established and confirmed in our faith, we shall be rooted and built up in Jesus, for it is faith which joins us to Him, and its increase measures our growth in and into Him.
There then is a very plain practical issue of these deep thoughts of union with Jesus. A progressive increase of our faith is the condition of all Christian progress. The faith which is already the firmest, and by its firmness may gladden an Apostle, is still capable of and needs strengthening. Its range can be enlarged, its tenacity increased, its power over heart and life reinforced. The eye of faith is never so keen but that it may become more longsighted; its grasp never so close but that it may be tightened; its realisation never so solid but that it may be more substantial; its authority never so great but that it may be made more absolute. This continual strengthening of faith is the most essential form of a Christian's effort at self-improvement. Strengthen faith and you strengthen all graces; for it measures our reception of Divine help.
And the furthest development which faith can attain should ever be sedulously kept in harmony with the initial teaching--"even as ye were taught." Progress does not consist in dropping the early truths of Jesus Christ the Lord for newer wisdom and more speculative religion, but in discovering ever deeper lessons and larger powers in these rudiments which are likewise the last and highest lessons which men can learn.
Further, as the daily effort of the believing soul ought to be to strengthen the quality of his faith, so it should be to increase its amount--"abounding in it with thanksgiving." Or if we adopt the reading of the Revised Version, we shall omit the "in it," and find here only an exhortation to thanksgiving. That is, in any case, the main idea of the clause, which adds to the former the thought that thanksgiving is an inseparable accompaniment of vigorous Christian life. It is to be called forth, of course, mainly by the great gift of Christ, in whom we are rooted and builded, and, in Paul's judgment it is the very spring of Christian progress.
That constant temper of gratitude implies a habitual presence to the mind, of God's great mercy in His unspeakable gift, a continual glow of heart as we gaze, a continual appropriation of that gift for our very own, and a continual outflow of our heart's love to the Incarnate and Immortal Love. Such thankfulness will bind us to glad obedience, and will give swiftness to the foot and eagerness to the will, to run in the way of God's commandments. It is like genial sunshine, all flowers breathe perfume and fruits ripen under its influence. It is the fire which kindles the sacrifice of life and makes it go up in fragrant incense-clouds, acceptable to God. The highest nobleness of which man is capable is reached when, moved by the mercies of God, we yield ourselves living sacrifices, thank-offerings to Him Who yielded Himself the sin-offering for us. The life which is all influenced by thanksgiving will be pure, strong, happy, in its continual counting of its gifts, and in its thoughts of the Giver, and not least happy and beautiful in its glad surrender of itself to Him who has given Himself for and to it. The noblest offering that we can bring, the only recompense which Christ asks, is that our hearts and our lives should say, We thank thee, O Lord. "By Him, therefore, let us offer the sacrifice of praise to God continually," and the continual thanksgiving will ensure continuous growth in our Christian character, and a constant increase in the strength and depth of our faith.
