(NWT) Jude 4 "My reason is that certain men have slipped in who have long ago been appointed by the Scriptures to this judgment, ungodly men, turning the undeserved kindness of our God into an excuse for loose conduct and proving false to our only Owner and Lord, Jesus Christ."

Eph 4:4-6 There is one body, and one Spirit, even as ye are called in one hope of your calling; 5 One Lord, one faith, one baptism, 6 One God and Father of all, who is above all, and through all, and in you all.

One Body= not two as the WT teaches (the little flock and the other sheep)

One Hope= not two as the WT teaches (the earthly hope and the heavenly hope)

One Lord= not two as the WT teaches (God the Father and the WT organization)

One God= not three as the WT teaches (the WT claims that Christians believe in three gods)

"You must be part of Jehovah’s organization, doing God’s will, in order to receive his blessing of everlasting life."

This makes the WT organization the channel of eternal life instead of a personal relationship with the Father through His Son Jesus Christ, the Eternal Son of God.  They shifted the authority to have eternal life from God to the WT organization.

Another piece of evidence that "taking in knowledge" is a mistranslation can be seen in their publication, (The Kingdom Interlinear Translation of the Greek Scriptures, 1969 ed, pg. 510).  Here it states,  "...they may be knowing you," which also implies a personal relationship.

The simple conclusion is that one can take in knowledge of a person all one's life and never personally know that person.  A boy who was raised by his father knows him very personally and likewise a person who is born of the Spirit into the family of God knows Him very personally.  Those who have never experienced this truth will never see the Kingdom of God regardless of who they are or the extent of their "good works." 

(NWT) John 3:3 "In answer Jesus said to him: Most truly I say to you, Unless anyone is born again, he cannot see the kingdom of God."

TRUE

Watchtower apologists lead one to think that the word "true" has some kind of "hidden, deep" meaning (in the Greek) that is not known to the average reader of scripture.  To see that this is just a smokescreen, anyone can go to other passages in John where the same word is used and get the idea that a comparison comes into mind.  For example: Jesus is said to be the true Light in John 1:9 as opposed to those who come as a false light.  Then in John 4:23 it speaks of true worshipers as opposed to false worshipers.  It doesn't take a deeper knowledge of the Greek to see this.  The real understanding comes from the context itself.

LIFE ETERNAL

John17:1-3 These words spake Jesus, and lifted up his eyes to heaven, and said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee:
2 As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him.
3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.

John 17:3 is a clarification of the previous verse and defines the term "eternal life."  The grammatical construction of John 17:3 provides the substance for and the basis of any interpretation that truly comes from the context without inserting any kind of WT bias that puts a spin on the verse.  The grammar shows everyone that eternal life is knowing the Father and Jesus Christ personally.
