Catholic20064,
The Book of Mormon was not described as a “superior book.” It was described as the “most correct of any book on earth”, and that people could “get nearer to God by abiding by its precepts, than by any other book.” You can find the same precepts in the Bible, but for many they are more easily understood and more readily accessible in clarity in the Book of Mormon.
As to your question, I thought of a quote when I read your question, which is included in the following set of quotes from Joseph Smith, followed by the link to the source:
Teachings of Joseph Smith about prayer:
"God will hear our prayers and speak to us today, just as He spoke to the ancient Saints.
“Seeing that the Lord has never given the world to understand by anything heretofore revealed that he had ceased forever to speak to his creatures when sought unto in a proper manner, why should it be thought a thing incredible that he should be pleased to speak again in these last days for their salvation?
“If one man can live upon the revelations given to another, might not I with propriety ask, why the necessity, then, of the Lord speaking to Isaac as he did, as is recorded in the 26th chapter of Genesis? For the Lord there repeats, or rather promises again, to perform the oath which he had previously sworn unto Abraham. And why this repetition to Isaac? Why was not the first promise as sure for Isaac as it was for Abraham? Was not Isaac Abraham’s son? And could he not place implicit confidence in the word of his father as being a man of God? Perhaps you may say that he was a very peculiar man and different from men in these last days; consequently, the Lord favored him with blessings peculiar and different, as he was different from men in this age. I admit that he was a peculiar man and was not only peculiarly blessed, but greatly blessed. But all the peculiarity that I can discover in the man, or all the difference between him and men in this age, is that he was more holy and more perfect before God and came to him with a purer heart and more faith than men in this day.
“The same might be said on the subject of Jacob’s history. Why was it that the Lord spake to him concerning the same promise after he had made it once to Abraham and renewed it to Isaac? Why could not Jacob rest contented upon the word spoken to his fathers?
“… I may believe that Enoch walked with God. I may believe that Abraham communed with God and conversed with angels. I may believe that Isaac obtained a renewal of the covenant made to Abraham by the direct voice of the Lord. I may believe that Jacob conversed with holy angels and heard the word of his Maker, that he wrestled with the angel until he prevailed and obtained a blessing. I may believe that Elijah was taken to heaven in a chariot of fire with fiery horses. I may believe that the saints saw the Lord and conversed with him face to face after his resurrection. I may believe that the Hebrew church came to Mount Zion and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels. I may believe that they looked into eternity and saw the Judge of all, and Jesus, the Mediator of the new covenant.
“But will all this purchase an assurance for me, or waft me to the regions of eternal day with my garments spotless, pure, and white? Or, must I not rather obtain for myself, by my own faith and diligence in keeping the commandments of the Lord, an assurance of salvation for myself? And have I not an equal privilege with the ancient saints? And will not the Lord hear my prayers and listen to my cries as soon as he ever did to theirs if I come to him in the manner they did?”
Sarah Granger Kimball reported: “In the School of the Prophets … , when Joseph Smith was giving instruction to the brethren, he told them to make everything they undertook a subject of prayer.”
“Seek to know God in your closets, call upon him in the fields. Follow the directions of the Book of Mormon, and pray over, and for your families, your cattle, your flocks, your herds, your corn, and all things that you possess [see Alma 34:18–27]; ask the blessing of God upon all your labors, and everything that you engage in."

No doubt Joseph Smith loved the Bible, and readily used it as a source for his encouragement to the LDS members to grow in their understanding and faithfulness.
And, it would also mean that the second part of the quote was completely inaccurate as well since it claims that one would get nearer to God through the BoM than through the Bible.
