I believe that God's human creations accept God by submitting to His will. I believe that a person can only submit to God's will in the fullest sense and meaning when they accept what He has most recently commanded. I believe that God restored the fulness of the Gospel of Jesus Christ in these last days, and that it is incumbent upon all people to recognize His voice in that Restoration and submit to it. I do not believe God is the Bible, nor do I believe that the composite of all that He has to reveal to His children is contained therein.
I think that one of the main differences between LDS and non-LDS is what each regards as a sufficient guide to eternal life.
For us, we believe that the Bible tells us that Christ is the only way, that He fully paid for the sins of believers, and that the Bible is a sufficient guide for instruction in righteousness. The Bible says that Christ makes His abode with believers and the Holy Spirit is given to them to remind them of truth, to empower them, and to know what God has freely given them.
But after that the kindness and love of God our Saviour toward man appeared, Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost.
Titus 3:4-5
Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God. Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual. But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
1 Corinthians 2:12-14
Now he which stablisheth us with you in Christ, and hath anointed us, is God; Who hath also sealed us, and given the earnest of the Spirit in our hearts.
2 Corinthians 1:21-22
LDS teaching is that the Bible alone is an
insufficient guide and that some who read it might stumble and come under the power of Satan because many covenants have been removed from it by men.
Nephi testified that the Bible once “contained the fulness of the gospel of the Lord, of whom the twelve apostles bear record” and that “after [the words] go forth by the hand of the twelve apostles of the Lamb, from the Jews unto the Gentiles, thou seest the formation of that great and abominable church, which is most abominable above all other churches; for behold, they have taken away from the gospel of the Lamb many parts which are plain and most precious; and also many covenants of the Lord have they taken away” (1 Nephi 13:24, 26).
Boyd K. Packer, “Who Is Jesus Christ?,” Ensign, March 2008, 12–19
There is an overwhelming lack of understanding in the world in relation to these principles of salvation and exaltation given to prepare mankind for a place in the kingdom of God, and this lack causes many to stumble. There is no excuse on the part of members of the Church, for they have received the necessary revelation directly from the heavens in this Dispensation of the Fulness of Times. The great mission of the Son of God has been revealed in the Book of Mormon and the Doctrine and Covenants more clearly than any other place. Many passages that have been misunderstood, and therefore mistranslated in the Bible, are clarified in these sacred volumes.
(Joseph Fielding Smith, Answers to Gospel Questions, 5 vols. [Salt Lake City: Deseret Book Co., 1957-1966], 4:.)

...because of these things which are taken away out of the gospel of the Lamb, an exceedingly great many do stumble, yea, insomuch that Satan hath great power over them.
Book of Mormon, 1 Nephi 13:29
Satan certainly wants people to stumble. On this LDS and Protestants can agree. Should a person be required to do more than what is set forth in the Bible or should a person not have added more commandments to those already revealed?
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
That the man of God may be perfect, throughly furnished unto all good works.
2 Timothy 3:16
Can the man of God be thoroughly furnished unto all good works through biblical instruction, or must he also follow the Doctrine and Covenants? The Doctrine and Covenants instructs men to do temple work, to achieve eternal families, that there are degrees of glory, etc. Are these teachings pertinent to one's salvation? The LDS would say they are. Without these teachings, they say "an exceedingly great many do stumble."
Wherefore, because that ye have a Bible ye need not suppose that it contains all my words; neither need ye suppose that I have not caused more to be written.
Book of Mormon, 2 Nephi 29:10
I do not believe that the Book of Mormon, the Pearl of Great Price, or the Doctrine and Covenants are revelations from God.
I have never met anyone who believes "God is the Bible," as you implied above. The Bible did not die for our sins!
