"Being built up in Him." The gradual continuous building up of the structure of a Christian character is doubly expressed in this word by the present tense which points to a process, and by the prefixed preposition represented by "up," which points to the successive laying of course of masonry upon course. We are the architects of our own characters. If our lives are based on Jesus Christ as their foundation, and every deed is in vital connection with Him, as at once its motive, its pattern, its power, its aim, and its reward, then we shall build holy and fair lives, which will be temples. Men do not merely grow as a leaf which "grows green and broad, and takes no care." The other metaphor of a building needs to be taken into account, to complete the former. Effort, patient continuous labour must be put forth. More than "forty and six years is this temple in building." A stone at a time is fitted into its place, and so after much toil and many years, as in the case of some mediæval cathedral unfinished for centuries, the topstone is brought forth at last. This choice, too, is before all men--to build on Christ and so to build for eternity, or on sand and so to be crushed below the ruins of their fallen houses. "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.
