Psalm 119:105 NUN. Thy word is a lamp unto my feet, and a light unto my path.
If the scripture is true, then all light is derived from it. Truth does not exist apart from the person of Christ. Therefore if one is truly seeking truth they will find Christ.
John 5:39 Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
The scripture is for the purpose of finding Christ. It is not a book to be used to fulfill ones own personal interests or gains. We are to seek out Christ for the purpose of fulfilling the purpose whereunto he has called us. It is not enough to do good, but to satisfy the will of the Father. To this end men should search the scripture.
Ecclesiastes 12:13 Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.
14 For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.
