I too was a bit hesitant in being open to the idea that She is 7, until one day last spring. The answer became clear to me one day while I was driving to work. I was pondering, "Why are believers the temples of the Ruach HaQodesh instead of temples of YHWH or temples of Yahushua?" Then the answer hit me over the head. We, at various times in our lives are ceremonially unclean. When one is ceremonially unclean, he or she cannot come into the temple of YHWH (when it was around). So since the Ruach HaQodesh is/are multiple Proxies for YHWH, then She/They cycle through us, ennabling us to be close to Abba YHWH because each of Her is in us at one time or another (providing we're not in outright rebellion), yet the other Her's are Echad with each other and Echad with YHWH. So it is necessary for Her/Them to be multiple in order for us to be in communion with YHWH and Yahushua.

This ia very beautiful and true concept and certainly it is our experience that different Ruachs minister in the different festivals and during different days of the week (themselves mini-reflections of the seven festivals). Most are aware that something 'special' and 'different' happens during the Sabbath but never consider that this might be one of the Seven Ruachs. specifically Shegal haShabbat, the Queen of the Sabbath. There are also seven overcomings the Book of Revelation says a believer must work through, and with each overcoming (I believe) comes a full manifestation of the Ruach connected with that overcoming. So in a way we go through multiple rebirths, beginning with Ruach haRishon (the first rebirth when a soul genuinely repents and accepts Yah'shua as Saviour into his/her heart) (paralleled by the moving of YHWH's spirit over the waters at creation leading to the first creative (or re-creative) act) and ending with the fullness of Shegal haShabbat at the final Sukkot or Marriage Feast of the Lamb when the whole planet enters into a sabbath rest.

Personally it is my testimony that coming to a knowledge of the true Ruach opens door after door of revelation, and that that revelation never ceases.
