Hello Perry,
I agree that the WTBTS is a works based faith. I am just not sure if the article you quoted from means what you say it does. Here is an entire section from the article.
Gathering the Things on Earth
10 Is it only anointed Christians who can experience a release by ransom, the forgiveness of their sins? No, God is reconciling to himself all other things by making peace through the blood shed on the torture stake, as Colossians 1:14, 20 indicates. This involves the things in the heavens (the 144,000) as well as the things upon the earth. The latter are those in line for earthly life, humans who will enjoy perfect life in Paradise on earth. Especially since 1935 has there been a concerted effort to gather such ones. Revelation 7:9-17 describes them as "a great crowd" who owe salvation to God and to the Lamb. They still need to survive "the great tribulation" and be 'guided to fountains of waters of life,' for Revelation 20:5 shows that such ones will become fully alive, having perfect human life, by the end of the Thousand Year Reign of Christ. Those who then pass a final test in their perfect human state will be declared righteous for everlasting life on earth.-Revelation 20:7, 8.
11 Nevertheless, in a preliminary way, the great crowd have already "washed their robes and made them white in the blood of the Lamb." (Revelation 7:14) Christ does not act as Mediator of the new covenant toward them, yet they benefit from this covenant through the work of God's Kingdom. Christ still acts toward them, however, as High Priest, through whom Jehovah can and does apply the ransom to the extent of their now being declared righteous as God's friends. (Compare James 2:23.) During the Millennium, they will gradually "be set free from enslavement to corruption [until finally they] have the glorious freedom of the children of God."-Romans 8:21.
12 As to their standing with God, it might seem that those of the great crowd differ little from pre-Christian worshipers. However, God dealt with the latter with the future ransom provision in view. (Romans 3:25, 26) They enjoyed forgiveness of their sins only in a provisional way. (Psalm 32:1, 2) Rather than fully relieving them of the "consciousness of sins," animal sacrifices caused "a reminding of sins."-Hebrews 10:1-3.
13 It is different with true Christians today. They worship on the basis of a ransom that has been paid! Through their High Priest, they "approach with freeness of speech to the throne of undeserved kindness." (Hebrews 4:14-16) Being reconciled to God is not some hoped-for development but a present reality! (2 Corinthians 5:20) When they err, they can receive real forgiveness. (Ephesians 1:7) They enjoy a truly cleansed conscience. (Hebrews 9:9; 10:22; 1 Peter 3:21) These blessings are a foretaste of the glorious freedom of the children of God that Jehovah's servants will enjoy in the future!
The way I see it the WTBTS is wrong because they say that Christ is not the mediator for all men. When that article says " work of God's Kingdom " isn't it referring to the work God's Kingdom will accomplish and not that you must work to gain salvation? I am not saying that they don't teach works over Grace, but I am not sure this paragraph is talking about having to personally work to gain life. If you were to show this to a JW, I believe they would mention what I have said. I am not sure that this particular point would get them thinking. The " mediator " false teaching should but we know how that goes.. I am interested in your thoughts on this.
