One of the reasons it is worded this way is due to the adoption of Adventist ideas by Jehovah's Witnesses. JWs limit all that is known about God to the physical universe because 1.) that is all that is explicitedly discussed in Scripture and 2.) time is an important factor to this religion, and it's theology demands that God be governed by the same laws of time that we are.
The Judeo-Christian concept of "God" is pre-Biblical and has itself evolved during the time of the Second Temple and up through the formal canonization of the New Testament, which was in the 4th century CE. These concepts, many of which are cultural and part of Jewry, are read into Scripture, especially into Liturgical proclamation.
Adentists and, by default, Jehovah's Witnesses reject almost all such historical theology as false because it is not explicitedly Biblical. There is no liturgy in either of these religions as a result, and therefore no connection to the cultures that formulated Scripture or direct access to any of their traditions. Witnesses would automatically reject such views anyway since there is no or little Biblical mention of them.
This is both problematic and illogical becuase without pre-Biblical ideas and an outside and greater authority than Scripture to dictate what is and what is not inspired Writ, the Bible itself could never exist. "True religion" would have to come first before there could be writers equipped enough to compose any texts. Scripture is produced by religion, not the basis for it. In this case the "chicken" has to exist before it can lay an "egg."
The Witnesses have a theology that limits God's revelation to what is written in the Bible. To them this superceeds the Great Theophany experienced by the Jews at the foot of Mt. Sinai (which is considered by Jews the greatest revelation they ever received), and is more authoritative than the Apostolic witness made up of those who lived side by side with Jesus Christ. In JW theology, only what is "written" is revelation, meaning any other words uttered by Christ are not as authoritative even if there is greater testimony from the Apostolic college or if ever archeological evidence came forth to verify the events of the Great Theophany. It has to be in the Bible or it is "bust"!
Becuase of this JWs have a very childish concept of the God of Abraham. JWs believe that "God" has a spirit body and lives in a "place" called Heaven. Both concepts, a spirit "body" and the belief that Heaven qualifies as a "place" are contrary and even somewhat forbidden as idolatry in Judaism. Both Judaism and Christianity believe spirits cannot possess bodies since a "body" is coporeal, which according to traditional theology is a thing that can only exist in a material state. "Spirit" by the original tradition defies being limited to a "body," as spirit belongs to the realm outside the temporal state where, according to the same tradition, there is no time or space.
Without such fundamentals essential to Judeo-Chrisitian thought, JW religion limits "God" to terminology such as "the universe," and refers to God as a being that has to have the ability to "foresee" events much like a psychic. Judeo-Christian views of God claim the universe as a "creation" making time and space things God created and thus not bound to. Becuase of this God does not need the power to "foresee" events in time as, being greater than time (which is a mere creation of God's), the past, present, and future are all immediately accessible at the same moment. These ideas are not directly found in Scripture as they are far older and were simply understood by the traditions that shaped and the cultures that employed these texts. Thus Watchtower-ism is void of them.
