4.  Thou art receiving not a perishable but a spiritual shield.  Henceforth thou art planted in the invisible Gr. νοητόν, i.e. the true Paradise, to be seen by the mind, not by the eye.  Apoc. xii. 7, 17. Paradise.  Thou receivest a new name, which thou hadst not before.  Heretofore thou wast a Catechumen, but now thou wilt be called a Believer.  Thou art transplanted henceforth among the spiritual See preceding note. olive-trees, being grafted from the wild into the good olive-tree Rom. xi. 24., from sins into righteousness, from pollutions into purity.  Thou art made partaker of the Holy Vine John xv. 1, 4, 5..  Well then, if thou abide in the Vine, thou growest as a fruitful branch; but if thou abide not, thou wilt be consumed by the fire.  Let us therefore bear fruit worthily.  God forbid that in us should be done what befell that barren fig-tree Matt. xxi. 19., that Jesus come not even now and curse us for our barrenness.  But may all be able to use that other saying, But I am like a fruitful olive-tree in the house of God:  I have trusted in the mercy of God for ever Ps. lii. 10.,—an olive-tree not to be perceived by sense, but by the mind νοητή, see note 1, above., and full of light.  As then it is His part to plant and to water 1 Cor. iii. 6.  When Paul plants and Apollos waters, it is God Himself who works through His ministers., so it is thine to bear fruit:  it is God’s to grant grace, but thine to receive and guard it.  Despise not the grace because it is freely given, but receive and treasure it devoutly.
