I. Stability.--He shall be like a tree (not a mere annual plant), of steady progressive growth and increasing fruitfulness. A tree planted, and always to be found in its place, not blown about, the sport of circumstances. The flowers may bloom and pass away, but the tree abides.

II. Independent Supplies.--Planted by the rivers of water. The ordinary supplies of rain and dew may fail: his deep and hidden supplies cannot. He shall not be careful in the year of drought, and in the days of famine he shall be satisfied. His supply is the living water--the SPIRIT of GOD--the same yesterday, today, and forever: hence he depends on no intermitting spring.

III. Seasonable Fruitfulness.--The careful student of Scripture will notice the parallelism between the teaching of the First Psalm and that of our LORD in the Gospel of John, where in the sixth chapter we are taught that he who feeds on CHRIST abides in Him, and in the fifteenth that he who abides brings forth much fruit. We feed upon CHRIST the incarnate WORD through the written Word. So in this Psalm he who delights in the Law of the LORD, and meditates upon it day and night, brings forth his fruit in his season.

There is something beautiful in this. A word spoken in season how good it is; how even a seasonable look will encourage or restrain, reprove or comfort! The promise reminds one of those in John about the living water thirsty ones drink, and are not only refreshed, but become channels through which rivers of living water are always flowing, so that other thirsty ones in their hour of need may find seasonable refreshment. But the figure in the Psalm is not that of water flowing through us as through a channel; but that of fruit, the very outcome of our own transformed life--a life of union with CHRIST.

It is so gracious of our GOD not to work through us in a mere mechanical way, but to make us branches of the True Vine, the very organs by which Its fruit is produced. We are not, therefore, independent workers, for there is a fundamental difference between fruit and work. Work is the outcome of effort; fruit, of life. A bad man may do good work, but a bad tree cannot bear good fruit. The result of work is not reproductive, but fruit has its seed in itself. The workman has to seek his material and his tools, and often to set himself with painful perseverance to his task. The fruit of the Vine is the glad, free, spontaneous outcome of the life within; and it forms and grows and ripens in its proper season.

And what is the fruit which the believer should bear? May it not be expressed by one word--Christliness? It is interesting to notice that the Scripture does not speak of the fruits of the SPIRIT, in the plural, as though we might take our choice among the graces named, but of the fruit, in the singular, which is a rich cluster composed of love, joy, peace, longsuffering, etc. How blessed to bring forth such fruit in its season!

IV. Continuous Vigour.--"His leaf also shall not wither." In our own climate many trees are able to maintain their life throughout the winter, but unable to retain their leaves. The hardy evergreen, however, not only lives, but manifests its life, and all the more conspicuously because of the naked branches around. The life within is too strong to fear the shortened day, the cold blast, or the falling snow. So with the man of GOD whose life is maintained by hidden communion through the Word; adversity only brings out the strength and the reality of the life within.

The leaf of the tree is no mere adornment. If the root suggests to us receptive power in that it draws from the soil the stimulating sap, without which life could not be maintained, the leaves no less remind us of the grace of giving, and of purifying. They impart to the atmosphere a grateful moisture; they provide for the traveller a refreshing shade, and they purify the air poisoned by the breathings of animal life.

Well, too, is the tree repaid for all that it gives out through its leaves. The thin stimulating sap that comes from the root, which could not of itself build up the tree, thickens in giving out its moisture, and through the leaves possesses itself of carbon from the atmosphere. Thus enriched, the sap goes back through the tree, building it up until the tiniest rootlets are as much nourished by the leaves as the latter are fed by the roots. Keep a tree despoiled of its leaves sufficiently long and it will surely die. So unless the believer is giving as well as receiving, purifying his life and influence, he cannot grow nor properly maintain his own vitality. But he who delights in the Law of the LORD, and meditates in it day and night--his leaf shall not wither.
