Then the ideas associated with a garden or the field are also used as illustrations. The Bible parables from nature are very significant and powerful. They embrace the vine and its branches, the sower and the seed, the lily among thorns, the trees planted by the rivers of water; and thus the facts of the spiritual realm are made clear to us.
I often speak of the garden of the soul. If I widen the figure, and apply it to our personal character and general make-up, we shall see the similitude of a garden which is a place where all sorts of things grow; things related to the body, and to the mind, and to life generally.
The gardener studies his ground, and the possible products and available seed. He seeks to get rid of the weeds and briers and poisonous plants, in order that the desired products may grow to perfection. So the ground of our hearts and characters must be purged from the weeds and hindering things which grow with the affections and disposition generally. Evil things flourish apace in the garden of human nature; but if they are removed, sanctified seed may be sown, and holy plants may be cultivated.
The Bible also speaks of God's saints as being in 'the garden of the Lord', as trees which His right hand planted, or growing from seed which He has sown, blossoming as the rose, fragrant as the honeysuckle and almond, and bringing forth the fruits of righteousness to the glory of His name. But whether you look at your souls as a garden, from which evil plants are to be removed, and in which the plants of God's grace are to flourish instead, or regard yourselves as trees in God's garden, the ideas are always connected with growth, enlargement, and productiveness.
Isaiah gives an illustration which is in striking contrast. Speaking of God's idea concerning His saints, he says, 'Thou shalt be like a watered garden, and a spring whose waters fail not'; but he supplies another picture of those 'who forsake the Lord' after having known Him, God saying to them, 'Ye shall be as an oak whose leaf fadeth, and as a garden that hath no water'. Let us look well at ourselves, and find out to which class we belong.
The religion of Jesus Christ is pre-eminently good because it marks things of evil growth as things to be rooted out, and it produces qualities in the soul and character which are Christ-like, such as love, forgiveness of injuries, patience, devotion, and self-sacrifice for the good of others. These are all things which grow, and must grow, if we are to be as God wants us to be. Cleansing from evil things we must definitely seek and secure; but growth in grace and peace and Divine knowledge, and skill in service, must be sought and cultivated by us continually.
It may help our understanding of this truth if we study carefully the process in the growth of a good tree. If there is satisfactory development, three things in the tree will be discovered; namely, growth in the root, growth in the branches, and growth in the form of flowers and fruit.
1. I said growth in the root. This means that the tree must strike deep, deeper, and deeper still, so as to get an increasingly firm grip on the earth below, from which it draws much of its support. Without this the tree will fall of its own top-weight, or be uprooted by the storms which will rage about it. So, in the individual soul and character there must, below the surface, be a deepening and spreading and gripping of the spiritual forces and principles and realizations, those hidden connexions with the Divine Unseen without which one cannot stand before the storms and scorching tests of life.
One of the sacred writers speaks of a section of God's people in trouble, and in danger of being wiped out, but reveals God's purpose for them in these words, 'They shall yet again take root downward, and bear fruit upward'. It is not difficult to grasp the principle illustrated; we must cultivate a religion with roots, otherwise our experience will be superficial and shallow, and, like the seed in the parable, with no depth of earth, and having little root, will ultimately become dried up.
This really means growth in secret, growth out of sight, and reminds us of the beautiful words of Jesus: 'When thou prayest, enter into thy closet; and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall Himself reward thee openly'. There are many kinds of prayer, but here is one that helps growth in the very roots of our religion. It fits in with the Psalmist's word, 'He that dwelleth in the secret place of the Most High shall abide under the shadow of the Almighty'.
