Per the WTS what has Noah's ark represented?
*** w83 2/15 p. 12 You Can Live Forever in Paradise on Earth—But How? ***
A third requirement is that we beassociatedwithGod’schannel, his organization. God has always used an organization. For example, only those in the ark in Noah’s day survived the Flood, and only those associated with the Christian congregation in the first century had God’s favor. (Acts 4:12) Similarly, Jehovah is using only one organization today to accomplish his will. To receive everlasting life in the earthly Paradise we must identify that organization and serve God as part of it.
*** w79 7/1 p. 23 Who Really Have the Truth? ***
Would God use more than one organization to dispense his truths in these "last days"? Well, has God ever used more than one during any other period of judgment? In Noah’s day, did any other boats with people in them, aside from Noah’s ark, have God’s protection and survive the flood? No, only the ark and its occupants did. (1 Pet. 3:20) Were there two Christian organizations in the first century? No, God dealt with just the one. So, too, in our day, there is still "one Lord, one faith, one baptism." (Eph. 4:5) That there could be only one united congregation is made clear from Paul’s words that "you should all speak in agreement, and . . . there should not be divisions among you."—1 Cor. 1:10.
*** w53 8/15 pp. 500-501 Living Now as a New World Society ***
The Kingdom means tighter organization for God’s people on earth. This is vitally necessary if we are to stand up against the combined forces of the enemy and overcome this world. No one can go it alone, and the King will not go it alone with such an individualist. He goes with his flock, his organized subjects. If we refuse organization instructions, if we forsake the gathering of ourselves together to avoid organization and its obligations, where could we go after Armageddon? Will there be separatists after Armageddon who will each make himself his own society and live as a hermit in a spacious earth, avoiding human contact and preferring animal society? For anyone to forsake the organized congregation of those who are destined to survive Armageddon means for that one never to get past Armageddon into the New World and its theocratic system. Like Noah’s family, we must now get into the ark all together!

Further, we share in Jehovah’s work for this day, a spiritual building work directed by the Greater Noah, Jesus Christ. As a place of security and survival, the ark represents the spiritual paradise that Jehovah has been building up among his worshipers since 1919. It is the condition of a restored peaceful relationship with God. It is His arrangement for preservation of the Greater Noah’s antitypical family through the "great tribulation."—Matthew 24:21; 1 Corinthians 3:9, 11; 2 Corinthians 12:3, 4; Revelation 7:13, 14.
