The WTS does jam it in from time to time. I remembered this from a review.

Do angels help Jehovah’s present-day servants? Yes, they do. Granted, today they do not appear visibly in order to deliver true worshipers from danger. Even in Bible times, angels only rarely intervened in such a way. Most of what they did was invisible to human eyes, as is the case today. Nonetheless, servants of God who realized that the angels were there to support them found such knowledge very encouraging. (2 Kings 6:14-17) We have good reason to feel similarly.

Jehovah’s angels are particularly interested in a special work that involves us. What work is that? We can find the answer at Revelation 14:6: "I saw another angel flying in midheaven, and he had everlasting good news to declare as glad tidings to those who dwell on the earth, and to every nation and tribe and tongue and people." This "everlasting good news" is clearly linked with the "good news of the kingdom," which, as Jesus foretold, "will be preached in all the inhabited earth for a witness to all the nations" before the end of this system of things. (Matthew 24:14) Of course, the angels are not preaching directly. Jesus gave humans this weighty commission. (Matthew 28:19, 20) Is it not good to know that as we fulfill that commission, we have help from holy angels, wise and powerful spirit creatures?

There is considerable evidence of angelic support for our work. For example, we often hear that in the course of their ministry, Jehovah’s Witnesses come across a person who had only recently prayed to God for help in finding the truth. Such experiences occur far too often to be dismissed as mere coincidences. As a result of such angelic help, more and more people are learning to do as the "angel flying in midheaven" proclaimed: "Fear God and give him glory."—Revelation 14:7.

Do you long to have the support of Jehovah’s mighty angels? Then do all you can to be absorbed in your ministry. (1 Corinthians 15:58) As we freely give of ourselves in this special assignment from Jehovah, we can count on the help of his angels.
