It is true that one needs the Spirit to properly interpret the Bible.
I really want to say yes, but I think the answer may be closer to yes and no, it depends. The Spirit produces belief in the Scriptures, generating an utmost value, utmost significance and reverence for the Scriptures in the hearts of believers. Unfortunately, it is also true that many non-believers have a greater intellectual understanding of Scripture than many believers. So one needs the Spirit, to have the proper heart for interpreting and receiving the blessings of the Spirit, such as the fear of the Lord, a life changing reverence for the Holiness of God and blessings such as confidence in the God of Scripture, which non-believers do not have.
But folks also have to believe what their Bible says in their own language, as well.
And that is a major problem today, too many play "choose your own adventure" with the Bible.
Sometimes certain folk try to redefine the Bible to what they want it to say with a dead language that they did not grow up writing or speaking. Words can be easy to fudge or change with a language that is not their own with another man's biased religious dictionary. But usually regular dictionaries in our own language are not so biased like that.
In general, I probably notice the
least bias in dictionaries, especially religious dictionaries, especially in dictionaries like Strong's for example, all of which are of great value. It is more common to find religious bias in a secularized dictionaries especially pertaining to religious meaning. However, dictionaries like the first American dictionary by Noah Webster, have an intended Christian bias, that is to be applauded.
Personally, in addition to prayer, the context and looking at older dictionaries helps a man or woman of God to understand what God's Word is saying. For God is simple; He is not complicated. His words are simple and pure and good.
I am sorry, but could not help but notice the comment "God is simple", which is something my own dad might say, but...simply is not true. Take the Chalcedonian Creed (451 A.D.) for example, it states:
"Following, then, the holy Fathers, we all unanimously teach that our Lord Jesus Christ is to us One and the same Son, the Self-same Perfect in Godhead, the Self-same Perfect in Manhood; truly God and truly Man; the Self-same of a rational soul and body; co-essential with the Father according to the Godhead, the Self-same co-essential with us according to the Manhood; like us in all things, sin apart; before the ages begotten of the Father as to the Godhead, but in the last days, the Self-same, for us and for our salvation (born) of Mary the Virgin
Theotokos as to the Manhood; One and the Same Christ, Son, Lord, Only-begotten; acknowledged in Two Natures unconfusedly, unchangeably, indivisibly, inseparably; the difference of the Natures being in no way removed because of the Union, but rather the properties of each Nature being preserved, and (both) concurring into One Person and One Hypostasis; not as though He were parted or divided into Two Persons, but One and the Self-same Son and Only-begotten God, Word, Lord, Jesus Christ; even as from the beginning the prophets have taught concerning Him, and as the Lord Jesus Christ Himself hath taught us, and as the Symbol of the Fathers hath handed down to us."
And we could go over other creeds the Nicene, Athanasian, Augustine's Trinitarian writings, other mountainous works on the attributes of God, and with all that we can know through Scripture and the great works by intellectual giants of the Christian faith, and as finite creatures still come to the conclusion that we do not and cannot know God exhaustively in all of His glory, that we see as through a glass darkly, and there remains mystery in God we will never comprehend this side of Heaven.
