First things first as they say.
2 Peter 1:20-21 (NASB95)
20 But know this first of all, that no prophecy of Scripture is a matter of one’s own interpretation,
21 for no prophecy was ever made by an act of human will, but men moved by the Holy Spirit spoke from God.
The Bible has a purpose. It is many things to many people. But its purpose is to convey absolute truth.
Human traditions which infest Bible study groups, churches, entire denominations, even the Body Christian as a whole to a certain degree impede the message God is trying to get through to mankind. All that truly matters is what the Holy Spirit (the author of the Bible) teaches.
John 16:13 (NASB95)
13 “But when He, the Spirit of truth, comes, He will guide you into all the truth; for He will not speak on His own initiative, but whatever He hears, He will speak; and He will disclose to you what is to come.
And there is a validation process which confirms absolute truth despite the claims of the traditionalists who by adding to the Word of God or taking away from it deluge truth with any number of traditions making the Bible appear schismatic, unreliable, subject to any fool's interpretation. The key is to illuminate the scriptures with the light of the Holy Spirit who inspired them (much like the original laser light used to create holograms). For it is entirely possible to read the Bible cover to cover and miss what the Holy Spirit teaches.
Any earnest study of the Bible begins with eliminating human traditions even we personally have (without realizing it at times) to get to what the Word of God truly says and means.
In a very real sense, the Word of God can simply be contained in the 10 Commandments. But our interpretation, understanding, application, etc. quite simply go against God's simple meaning. The Word of God can be narrowed down to the commentary on the 10 Commandments Jesus gave:
Matthew 22:36-40 (NASB95)
36 “Teacher, which is the great commandment in the Law?”
37 And He said to him, “ ‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’
38 “This is the great and foremost commandment.
39 “The second is like it, ‘You shall love your neighbor as yourself.’
40 “On these two commandments depend the whole Law and the Prophets.”
"Law and Prophets" is an old Hebrew idiom for the entire Bible.
What a world this would be if we simply applied these two commands. America, when it was blessed and functioning properly summed this up in the secular version called the Golden Rule.
Back to the Bible:
In anticipation of human tradition, misunderstanding and just plain hostile interference, God designed his Word stealthily.
Proverbs 25:2 (NASB95)
2 It is the glory of God to conceal a matter, But the glory of kings is to search out a matter.
Deuteronomy 29:29 (NASB95)
29 “The secret things belong to the Lord our God, but the things revealed belong to us and to our sons forever, that we may observe all the words of this law.
Isaiah 28:9-13 (NASB95)
9 “To whom would He teach knowledge, And to whom would He interpret the message? Those just weaned from milk? Those just taken from the breast?
10 “For He says, ‘Order on order, order on order, Line on line, line on line, A little here, a little there.’ ”
11 Indeed, He will speak to this people Through stammering lips and a foreign tongue,
12 He who said to them, “Here is rest, give rest to the weary,” And, “Here is repose,” but they would not listen.
13 So the word of the Lord to them will be, “Order on order, order on order, Line on line, line on line, A little here, a little there,” That they may go and stumble backward, be broken, snared and taken captive.
So now comes the critical process of determining IF the spirit you perceive as the Holy Spirit is actually the one illuminating the Bible as you study... since we are such poor judges of truth (the longer one lives the more we realize this is a fact)...
1 Thessalonians 5:21 (NASB95)
21 But examine everything carefully; hold fast to that which is good;
1 John 4:1 (NASB95)
1 Beloved, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world.
Acts 17:11 (NASB95)
11 Now these were more noble-minded than those in Thessalonica, for they received the word with great eagerness, examining the Scriptures daily to see whether these things were so.
See the cyclical nature of this? To validate scripture, seek the tutelage of the Holy Spirit. To validate it is the Holy Spirit teaching you, test the spirits by scripture.
2 Timothy 3:16-17 (NASB95)
16 All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness;
17 so that the man of God may be adequate, equipped for every good work.
In fact the Bible is the standard for truth. You've seen rulers as the standard for measure of feet and inches. This is the ruler for all truth.
John 17:17 (NASB95)
17 “Sanctify them in the truth; Your word is truth.
Seek truth with the passion your heart desires or learn to create such passion... big part of not having the "hard heart" as it is described in the Old Testament is to passionately seek the absolute (real) truth, and to apply faith (belief AND understanding what God is teaching you as you grow in the knowledge of God). And you will be among those whom the LORD elects and chooses to set the world on fire with your walk with him.
God bless!
