A - Thanks for the question. Well, the first thing I would say is that if this is the case, there could be an issue with how the person is reading the Bible if they aren't getting anything out of reading the Bible. If we truly believe that the Bible contains the written revelation of all that God wanted to reveal to us about Himself, our relationship to Him, and our salvation, then there is no good reason not to read (and pray with) the Bible. But, we still must learn how to do so effectively and prayerfully. This takes time and practice.
The Bible is not a history textbook, a novel, or like any other piece of literature. It is God-breathed. It is an opportunity to encounter Christ. It is the primary way we can know about the life of Jesus. It is God's Word to us in the written form. So, maybe getting someone who is knowledgeable about how to pray with the Bible to help teach some ways to enter into prayer with the Bible would be a good idea.
As St. Jerome said, "Ignorance of Scripture is Ignorance of Christ". Do we want to know Jesus intimately? Then we cannot just brush aside the Bible as something that doesn't fit our fancy. From the sound of your question this person has not given the Bible a fair shake or they don't know how to really dive into The Word of God in the Bible, because they have only read "parts of the Bible". Maybe this quote from Vatican II's Constitution on The Word of God can help shed some light on the importance of reading the Bible for every Catholic (emphasis added):
The Church has always venerated the divine Scriptures just as she venerates the body of the Lord, since, especially in the sacred liturgy, she unceasingly receives and offers to the faithful the bread of life from the table both of God's word and of Christ's body. She has always maintained them, and continues to do so, together with sacred tradition, as the supreme rule of faith, since, as inspired by God and committed once and for all to writing, they impart the word of God Himself without change, and make the voice of the Holy Spirit resound in the words of the prophets and Apostles. Therefore, like the Christian religion itself, all the preaching of the Church must be nourished and regulated by Sacred Scripture. For in the sacred books, the Father who is in heaven meets His children with great love and speaks with them; and the force and power in the word of God is so great that it stands as the support and energy of the Church, the strength of faith for her sons, the food of the soul, the pure and everlasting source of spiritual life. Consequently these words are perfectly applicable to Sacred Scripture: "For the word of God is living and active" (Heb. 4:12) and "it has power to build you up and give you your heritage among all those who are sanctified" (Acts 20:32; see 1 Thess. 2:13).Scripture should be an indispensable part of every Christians' daily life. As the quote above shows us, it is a way we meet, talk, and receive grace from the Father.
I hope this helps.
