The source of all intellectual and spiritual gifts
The physical manifestations are not the most important effects of Ruach-infilling, nor are they a necessary proof of it.
The Ruach is the source of all intellectual and spiritual gifts, whether they be the artistry of Bezaleel Shemoth (Exodus) 31:2-3 "See, I have called by name Bezaleel the son of Uri, the son of Hur, of the tribe of Judah: And I have filled him with the Ruach Ha Kodesh of YAHWEH, in wisdom, and in understanding, and in knowledge, and in all manner of workmanship," or the Understanding and Wisdom with which Daniel interpreted dreams. Daniel 5:14 "I have even heard of you, that the Ruach of the ALMIGHTY is in you, and that light and understanding and excellent wisdom is found in you."
It is the inspiration of the men of wisdom and so can be identified with the WISDOM OF YAHWEH. The effects of the operation of the Ruach are seen by the great prophets, not merely in the manifestation of the enthusiast, but in the permanent establishment of judgment of sin, justice and righteousness among the people of YAHWEH.
Transformation into a place of righteousness
This transformation of the world into a place of righteousness is expected in the days when "YAHWEH's Ruach Ha Kodesh is poured upon us from on high." YeshaYahu 32:15 "Until the Ruach be poured upon us from on high, and the wilderness be a fruitful field, and the fruitful field be counted for a forest." It is the guarantee and sign of the Covenant promises of YAHWEH. Haggai 2:5 "According to the Word that I Covenanted with you when you came out of Egypt, so My Ruach remained among you: fear not." and of their fulfillment in the acts of YAHWEH toward the restored community. Zechariah 4:6 "Then he answered and spoke unto me, saying, This is the Word of YAHWEH unto Zerubbabel, saying, Not by might, nor by power, but by My Ruach Ha Kodesh, said YAHWEH of hosts."
The moving of YAHWEH in SetApartness
Above all, the Ruach is the moving of YAHWEH in SetApartness, both of the Covenant people, YeshaYahu 59:21 " As for Me, this is My Covenant with them, said YAHWEH; My Ruach Ha Kodesh that is upon you, and My words which I have put in your mouth, shall not depart out of your mouth, nor out of the mouth of your seed, nor out of the mouth of your seed's seed, said YAHWEH, from henceforth and for ever." who will be enabled by their infilling of the Ruach within them to observe the Commandments of YAHWEH, Yehezqel 36:27 "And I will put My Ruach within you, and cause you to walk in My statutes, and you shall keep My judgments, and do them." Yehezqel 39:29 "Neither will I hide My face any more from them: for I have poured out My Ruach upon the house of Yisrael, said the Sovereign YAHWEH." and of the individual, who may pray: Tehillim 51:10-11 "Create in me a clean heart, YAHWEH, and put a new and right Ruach within me. Cast me not away from Your presence, and take not Your Ruach Ha Kodesh from me."
