AT NO TIME in the process of maturity does the tree become independent of the information and instructions the seed provides. In fact, new, correct, and true, information is necessary from the sun, rain, soil and even the bees–all coordinated for the benefit of the tree by the masterful instructions in the seed.
Now the parable is this:
The seed is the word of God. Luke 8:11 KJV
It is the spirit that quickeneth [gives life]; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life. But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him. John 6:63-64 KJV
“I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing. If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned. If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you. Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples. —John 15:5-8 KJV
