Blessed is the man that walketh
not in the counsel of the ungodly, nor standeth in the way of sinners,
nor sitteth in the seat of the scornful. But his delight is in the law
of the LORD; and in his law doth he meditate day and night. And he shall
be like a tree planted by the rivers of water, that bringeth forth his
fruit in his season; his leaf also shall not wither; and whatsoever he
doeth shall prosper.
Psalm 1:1- 3
"Trees are given a prominent position in God’s Word. Psalm 1
compares a man who bases his life on God’s law to a tree growing close
to streams of water, which yields its fruit in season and whose leaf
does not wither.
Compare a tree with a skyscraper, often seen as a supreme example of
human achievement. A skyscraper begins with a plan, 
compiled by a team
of architects and engineers.
Even a very large tree begins with a tiny
seed, often no bigger than a pinhead. But it is crammed with complex
programmed information that controls its development into a living giant.
It takes a mountain of materials such as cement, sand, and steel to
be brought to the site to build a skyscraper.
But the tree seedling
accomplishes the build-up of its body—the root system, the bole (trunk)
and the crown—on site, just utilizing raw materials surrounding it. It
uses the water delivered by the rain, the carbon dioxide and the oxygen from the surrounding air, and the nutrients dispersed through the soil around its roots.
Not only that, but the energy that makes possible the building of its
impressive structure does not have to be generated elsewhere and
channeled to the building site. The energy of the sun is captured by
special organs of the trees, called leaves. These small, green, and
mostly flat, leathery structures contain thousands of minute but highly
sophisticated factories capable of capturing solar energy and converting
it into energy-rich substances. The tree uses these to build its body
and to perform its many functions.
In our economies, we struggle with the problem of disposing of 
waste
products. But in trees this is dealt with neatly and efficiently by this
fixation of solar energy. The by-product of this process is oxygen,
which is essential for animal (and plant) life. It is released from the
tree’s leaves to the atmosphere via the same access pores (stomata)
through which the key raw material, the carbon dioxide, is taken in.
The crown of the tree is so designed as to give the leaves maximum
exposure to the source of energy, the sun. Every photosynthesizing cell
in the leaves is connected to the rest of the tree by minute conducting
channels. One set, xylem, conducts water and dissolved chemicals upwards from the roots to the leaves. The other set, phloem,
conducts the sugars produced in the leaves downwards to the roots. Both
types are formed within the tree from the sugars generated from
sunlight, reconstituted into strong and stable substances called
cellulose and lignin.
The root system of a tree likewise has a dual function. It anchors the
tree into the soil and extracts water and nutrients from it. When it
rains, some of the water directly enters through the leaf surfaces, but
most ends up in the ground. A tree needs to obtain large amounts of
water to survive and flourish. Its roots actively search for and extract
it, along with dissolved nutrients, from the soil for despatch to the
crown.
What is clear from all this is the superiority of the divine design. "
