ROOT SYSTEM: Roots are necessary to anchor and supply nutrients to the plant. Psalms chapter l tells how to develop the root system in your spiritual life:
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. (Psalms 1:1-3) SOIL: Both in the natural and spiritual worlds, in order to produce fruit the ground must be properly prepared. In the parable of the sower in Matthew 13 it was the condition of the soil that affected the growth of the seed. Your heart is like soil in the natural world. If your heart is hard and filled with things of the world that choke out the Word of God, you will not bear spiritual fruit.
It is your responsibility to prepare the spiritual soil of your heart to respond properly to God's Word:
Sow to yourselves in righteousness, reap in mercy; break up your fallow ground: for it is time to seek the Lord, till He come and rain righteousness upon you. (Hosea 10:12)
