To add to TD's comment:
Awake! 1999, 2/8, p. 9, Identifying the Only True God
Getting to know the only true God in this way is really a never-ending process, as is brought out clearly in the rendering of John 17:3 in the New World Translation of the Holy Scriptures. Here the correct tense of the verb “to know” helps greatly, for the present continuous tense is used rather than the simple present tense. Hence, we read: “This means everlasting life, their taking in knowledge of you, the only true God, and of the one whom you sent forth, Jesus Christ.” Yes, continuing to take in knowledge of the only true God, Jehovah, and of his Son, Jesus Christ, is a process that should never end.
