My father planted a tree many years ago, a pin oak tree on his property by his house. He commented to me the other day about how very large this tree has grown and how he has never seen this type of tree grow so tall.
About 15 years ago my dad and I dug a koi pond just beside this tree. Lately there has been a hidden leak in the liner of that pond that has been slowly watering and fertilizing the pin oak for several years now. The visible difference in this tree that was being well watered by the pond is remarkable.
 Blessed is the man who walks not in the counsel of the wicked, nor stands in the way of sinners, nor sits in the seat of scoffers;  but his delight is in the law of the LORD, and on his law he meditates day and night.  He is like a tree planted by streams of water that yields its fruit in its season, and its leaf does not wither. In all that he does, he prospers. (ESV) Psalm 1:1-3
 “Blessed is the man who trusts in the LORD, whose trust is the LORD.  He is like a tree planted by water, that sends out its roots by the stream, and does not fear when heat comes, for its leaves remain green, and is not anxious in the year of drought, for it does not cease to bear fruit.” (ESV) Jeremiah 17:7-8
Blessed is the man.
Who delights in the law of the LORD and medicates on it day and night.
Who trusts in the LORD.
That tree was gaining sustenance from the pond. God’s word tells us to do likewise and gain sustenance from His Word. God became flesh. His word became flesh and dwelt among us. He is our daily bread. He is our living waters. He provides us His Holy Spirit to sustain and guide us. Our sustenance comes from His Word.
One of my regular duties that I detest is meal preparation. I shouldn’t complain as it is much easier for me than for most, however, I see the toil and the never ending need for it. Every day it takes time and effort and resources to provide the needed food. It is the same for our spiritual food. It takes time and effort and resources to feed properly on the Word of God. If we expect to grow tall like that pin oak, we need to be consistently feed and watered with it. It is our spiritual food. It keeps us from being anxious in times of trial and drought. It allows us to continue to be effective in our efforts for God as His servants – to bear fruit continually.
So send out your roots by the streams of living water that Christ Jesus has for you and drink deeply every day. If you persists in this, you will become a spiritual giant, visibly displaying God’s glory and power to all those around you. Be encouraged. Press on.
