The Bible reveals God as omniscient; that is,
“God, being infinite, is able to be aware of all things, to understand all things, and to comprehend all things. He never learns anything or acquires new knowledge. The future as well as the past and present are completely known by Him.” (R.C. Sproul, Essential Truths of the Christian Faith)
Put another way,
“God fully knows himself and all things actual and possible in one simple and eternal act…
“Here the word ‘simple’ is used in the sense of ‘not divided into parts.’ This means that God is always fully aware of everything…he always knows all things at once. He does not have to reason to conclusions or ponder carefully before he answers, for he knows the end from the beginning, and he never learns and never forgets anything…
“[‘Eternal act’] simply means that God’s knowledge never changes or grows. If he were ever to learn something new, he would not have been omniscient beforehand. Thus, from all eternity, God has known all things that would happen and all things that he would do.” (Wayne Grudem, Bible Doctrine)
Mormonism entertains conflicting views regarding God’s omniscience. Fourth LDS Prophet Wilford Woodruff, for example, taught that
“GOD IS INCREASING IN KNOWLEDGE. If there was a point where man in his progression could not proceed any further, the very idea would throw a gloom over every intelligent and reflecting mind. God Himself is increasing and progressing in knowledge, power, and dominion, and will do so, worlds without end.” (The Discourses of Wilford Woodruff, 3)
But another LDS Prophet taught,
“It seems very strange to me that members of the Church will hold to the doctrine, ‘God increases in knowledge as time goes on.’… Where has the Lord ever revealed to us that he is lacking in knowledge? That he is still learning new truth; discovering new laws that are unknown to him? I think this kind of doctrine is very dangerous.” (Joseph Fielding Smith, Doctrines of Salvation, 1:7-8)
In February (2010) the blog Mormon Matters took a poll of its readers asking “Is God Still Progressing?” Eighty-two percent of the respondents said they believe God is still learning and progressing.
The question of God’s omniscience was addressed at the LDS FAQ section of the BYU website.
“Q. How can God be all-knowing and still progress eternally?”
The supplied answer might not be as helpful as some “confused students” may hope.
“A. An article by James R. Harris [BYU Studies] explains that some students have been confused by apparently conflicting statements made by early Church leaders about God’s omniscience on the one hand and his ability to grow in knowledge and glory on the other. These leaders recognized that God could somehow grow in knowledge and at the same time experience no deficiency in his knowledge, being, in fact, a possessor of all knowledge. God’s foreknowledge spans all of man’s experience (premortal, mortal, post-mortal, and immortal) and man’s end (his final condition as an individual) is known by God, ‘from the beginning.’ This foreknowledge may have come as a result of God’s long observation of his children through premortal ages or eons, or it may come as a result of the celestial globe where God resides and where things past, present, and future are continually before the Lord. In this sense, God’s knowledge is perfect. Eternal progression, like eternal life, may represent a quality of experience and not exclusively a duration of experience. The mind of our God is in constant and perfect union with all that is divine throughout the immensity of space. Our Lord, Jesus Christ, has the character of a God and under the law of consecration, he is the possessor of all things. All that God possesses in wisdom, knowledge, and power, are his through a union of property among all Exalted Fathers. Thus, as the Lord moves to ever higher degrees of exaltation, a constant flow of knowledge and power will be called forth from what Harris calls the ‘Grand Union of Divine Minds.’ Harris suggests that while God is progressing in knowledge, there is never a practical deficiency in his knowledge because of his immediate access to the experience and knowledge of all divine beings.”
Joel Groat at Institute for Religious Research’s Facebook page observed that this BYU Studies answer
“Makes clear two things: 1. When it comes to God in Mormonism there is not just one and only one unique divine being (historic, biblical Judaism and Christianity), and 2. Unlike the God of the Bible, the God of Mormonism is dependent on other divine beings (Exalted Fathers) for his omniscience and omnipotence.”
If the answer provided by BYU is any reflection of true Mormonism, it’s pretty clear that the God of that religion is not worthy of the words of praise penned by Paul found in the Bible:
Oh, the depth of the riches and wisdom and knowledge of God!
How unsearchable are his judgments and how inscrutable his ways!
“For who has known the mind of the Lord,
or who has been his counselor?”
“Or who has given a gift to him
that he might be repaid?”
For from him and through him and to him are all things.
To him be glory forever. Amen.
