Have you forgotten your bible teaching? Or is this some new JW doctrine I've never heard before?
Matthew chapter 18
The Greatest in the Kingdom
And He called a child to Himself and set him before them, and said, "Truly I say to you, unless you are converted and become like children, you will not enter the kingdom of heaven. "Whoever then humbles himself as this child, he is the greatest in the kingdom of heaven....
Luke chapter 18
But Jesus called for them, saying, "Permit the children to come to Me, and do not hinder them, for the kingdom of God belongs to such as these. "Truly I say to you, whoever does not receive the kingdom of God like a child will not enter it at all."
Mark chapter 10
And they brought young children to him, that he should touch them: and his disciples rebuked those that brought them. But when Jesus saw it, he was much displeased, and said unto them, Suffer the little children to come unto me, and forbid them not: for of such is the kingdom of God. Verily I say unto you, Whosoever shall not receive the kingdom of God as a little child, he shall not enter therein. And he took them up in his arms, put his hands upon them, and blessed them.
From one of your favorite books, Ecclesiates, chapter 12
1 - Remember now thy Creator in the days of thy youth, while the evil days come not, nor the years draw nigh, when thou shalt say, I have no pleasure in them; While the sun, or the light, or the moon, or the stars, be not darkened, nor the clouds return after the rain: In the day when the keepers of the house shall tremble, and the strong men shall bow themselves, and the grinders cease because they are few, and those that look out of the windows be darkened, And the doors shall be shut in the streets, when the sound of the grinding is low, and he shall rise up at the voice of the bird, and all the daughters of musick shall be brought low; Also when they shall be afraid of that which is high, and fears shall be in the way, and the almond tree shall flourish, and the grasshopper shall be a burden, and desire shall fail: because man goeth to his long home, and the mourners go about the streets: Or ever the silver cord be loosed, or the golden bowl be broken, or the pitcher be broken at the fountain, or the wheel broken at the cistern. Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
