(1.) Shall be growing. The bad being by the grace of God made good, they shall by the same grace be made better; for grace, wherever it is true, is growing. [1.] They shall grow upwards, and be more flourishing, shall grow as the lily, or (as some read it) shall blossom as the rose. The growth of the lily, as that of all bulbous roots, is very quick and speedy. The root of the lily seems lost in the ground all winter, but, when it is refreshed with the dews of the spring, it starts up in a little time; so the grace of God improves young converts sometimes very fast. The lily, when it has come to its height, is a lovely flower (Matt. vi. 29), so grace is the comeliness of the soul, Ezek. xvi. 14. It is the beauty of holiness that is produced by the dew of the morning, Ps. cx. 3. [2.] They shall grow downwards, and be more firm. The lily indeed grows fast, and grows fine, but it soon fades and is easily plucked up; and therefore it is here promised to Israel that with the flower of the lily he shall have the root of the cedar: He shall cast forth his roots as Lebanon, as the trees of Lebanon, which, having taken deep root, cannot be plucked up, Amos ix. 15. Note, Spiritual growth consists most in the growth of the root, which is out of sight. The more we depend upon Christ and draw sap and virtue from him, the more we act in religion from a principle and the more steadfast and resolved we are in it, the more we cast forth our roots. [3.] They shall grow round about (v. 6): His branches shall spread on all sides. And (v. 7) he shall grow as the vine, whose branches extend furthest of any tree. Joseph was to be a fruitful bough, Gen. xlix. 22. When many are added to the church from without, when a hopeful generation rises up, then Israel's branches spread. When particular believers abound in good works, and increase in the knowledge of God and in every good gift, then their branches may be said to spread. The inward man is renewed day by day.
