The fact that Jehovah's Witnesses seek greater understanding should be of comfort to people, because we are not afraid to admit that we are human and "those taking the lead among [us]" are born into sin and therefore imperfect. (Romans 3:23; Hebrews 13:7) But I suppose that people do not want to know that those who are taking the lead among them are fallible. They want to believe that their leaders are infallible. They want to believe that everything they believe is 100% accurate. The problem is, with humans in charge, that is impossible at this time.
It is, in fact, the height of arrogance for any human or human organization to state or imply that they are infallible.
"Now We See in Hazy Outline...Then it Will Be Face-to-face."In order to find that truth, one has to study and attempt to draw conclusions. Those conclusions cannot be assumed to be infallible. We must seek to answer hard questions and yes the organization has often been wrong in the past, and yes there continue to be adjustments in understanding, sometimes multiple times on the same subject. That is the process it takes to get at the truth, because we figure out one thing at a time, but often something like the wheat and the weeds, the separating of sheep and goats and who are "the faithful and discreet slave" are made up of many smaller details. It is those details we come to understand more and more of, which adjusts are understanding of the bigger picture. As we come to understand the true meaning of those details, we do not change our understanding of the details later, but we may get clearer understanding on other details that we may have missed or that have received a new understanding due to understanding something else more clearly.
While those details are coming clear, we may have a misunderstanding about the bigger picture, such as when looking down a road in the distance on a hot day, leading to your house. The distortions and mirages of evaporating water causes you not to be able to discern details clearly. As a person walks closer to you, you may think at first that it is a dog walking in the distance. But as they come closer, we see that it is in fact a person wearing a brownish-red shirt, and may think, "Oh that's Jorge's favorite color, it must be him." What details did we have correct to start? It's a living thing and it is walking, but then you perceived the details of form and color. But then they come closer and you realize that their walking gate is feminine and they have long hair. As they draw closer, you speculate, "It's got to be Veronica", then "It's Teresa!", but finally, you figure out that you do not know the woman in the brownish-red business suit and figure out that there are details that only the woman can tell you. Regardless of what those details are, you went through a lot of guesses about who or what she was. The details of a living human woman wearing a brownish-red business suit are all correct, but you did not see many of those details right away, but had to wait until they became clear. Other times, you may figure out who it is at a distance and even understand why they are there before they ever reach you. Point being that if you stay on the watch, you will not be caught off guard or miss anything important. (Mark 13:28-37; compare Matthew 25:1-13)
In "guiding" us, the spirit does not give us information we would not otherwise find. Why? Because Christians today have not been granted the privilege of the gifts of prophecy or knowledge, nor in receiving a visit from Jesus or the angels. (1 Corinthians 13:8-12) The knowledge must be accessible to us, but the spirit still needs us to uncover the specific details. In the meantime, we must continue to focus and to make an effort to understand, or else we may be found to be sleeping when the Son of Man comes to destroy Satan's system. (Mark 13:32-37)
Humbly Seeking TruthIt comforts me that improved understanding is sought for the very reason that I know the leadership are all humans trying their best to understand God's word. But in all other organizations, the leadership claims to be infallible, which only scares me. They are humans. It is not possible for them to be infallible.
The Scriptures themselves say that we should continually search after truth, (Proverbs 4:18) so it is a fallacy to claim that one already has the whole of the truth without error. Peter himself recognized, humbly, that there was room to learn when he said: "Consequently WE have the prophetic word [made] MORE SURE...For you all know this first, that NO PROPHECY OF SCRIPTURE SPRINGS FROM ANY PRIVATE INTERPRETATION. For PROPHECY WAS AT NO TIME BROUGHT FROM MAN'S WILL, but men spoke from God as they were borne along by holy spirit." (2 Peter 1:19-21)
Really, though, how many different organizations can be infallible if they have directly conflicting doctrines with each other? Obviously, they can't all be right. In fact, only one can be right, and not even that is likely. But there can be just one who is chosen by God, just as God only ever used one organization up to the death of the apostle John.
So for any religious organization to claim they are infallible is first lacking humility and is second refusing to recognize their need for the ransom provision of Jesus Christ, which would automatically disqualify them to receive Jehovah's spirit. (1 John 2:2; Hebrews 7:11; James 4:6) We are imperfect and we cannot understand God's word perfectly nor administer it perfectly until we have been made mentally and spiritually perfect and God chooses to reveal all things to us. But not even Jesus, the second person in the universe, knew all things. (Mark 13:32) Jesus said in prayer to his Father: "I publicly praise you, Father, Lord of heaven and earth, because you have carefully hidden these things from wise and intellectual ones, and have revealed them to babes." (Luke 10:21) If those to whom he is revealing those things are babes, then they are not adults, and are thus still learning. Indeed, Jesus again said: "Therefore, whoever will humble himself like this young child is the one that is the greatest in the kingdom of the heavens; and whoever receives one such young child on the basis of my name receives me [also]." (Matthew 18:4-5)
Think about it. Can God's organization (whichever you believe that to be) know everything? (Matthew 24:36) Should they not seek greater understanding of God's word? (Daniel 12:4) When the disciples began their preaching work in the first century, did they have the whole canon of Scriptures we have today? Of course not. It was revealed to them over time, and which they wrote down. (Acts 15:6-23) But then the truth became muddled by apostate Babylonish teachings after "he that [was] acting as a restraint [got] to be taken out of the way," (2 Thessalonians 2:1-12) who turned out to be the last remaining apostle, John; when he died, the truth became suppressed by "the church". (1 Timothy 4:1-5; 2 Timothy 4:3-5; Romans 1:18-32) So there was a need to slowly uncover the truth once again. With all these organizations in the world calling themselves the true Christian organization, it is certainly not any that claims to be infallible or never seeks to adjust its teachings to more closely conform to the Scriptures.
