What Is the Bible and Why Does It Matter to Your Daily Walk?

Mike Mahaffey

The Bible is the written Word of God — sixty-six books, one Author, one message. It exists to lead you into a living relationship with Jesus Christ and to show how the Cross applies to the life you are actually living, not just to pass on religious information.

What Is the Bible?

The Bible is God speaking in written form. Sixty-six books, over forty writers, one Author behind all of them.

All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness. (2 Timothy 3:16)

“Inspiration” here means God-breathed. The words originated with God, not with the men who held the pen.

That is not a claim about a book being useful. It is a claim about where the book came from.

Why Does the Bible Matter to Your Daily Walk?

The Word of God is not background reading. It is the instrument the Holy Spirit uses to work in a believer’s life every day.

For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. (Hebrews 4:12)

“Quick” means alive. Scripture is not a record of what God once said. It is what God is saying to you right now.

What Does the Bible Say About Itself?

Scripture testifies to its own nature. Two passages say the same thing from different angles.

2 Timothy 3:16 says God is the source. 2 Peter 1:20–21 says the human writers were carried along, not writing their own opinions.

Knowing this first, that no prophecy of the scripture is of any private interpretation. For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost. (2 Peter 1:20–21)

The Bible’s authority does not rest on how confident you feel about it. It rests on the character of the One who spoke it.

Why You Need the Holy Spirit to Understand the Bible

Reading the Bible and receiving what it says are two different things. A person can read every chapter and still miss the point.

But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned. (1 Corinthians 2:14)

The Holy Spirit is not optional equipment for Bible study. He is the Author, and only the Author can fully explain what He wrote.

I used to think a study Bible and enough effort would get me there on my own. It won’t — not without Him doing the actual illuminating.

How to Read and Study the Bible for Yourself

The Bible rewards a reader who comes to it with a method, not a system. That means an open Bible, a willingness to be corrected, and patience.

Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth. (2 Timothy 2:15)

“Rightly dividing” means handling the text with care. Know who is speaking, who is being spoken to, and what covenant is in view before deciding what a verse means for you.

A verse pulled out of its context can be made to say almost anything. Left in its context, it only ever says one thing — and getting there is the actual discipline of study.

How Do You Know if a Bible Promise Applies to You?

Not every promise in Scripture was made to you. Some were made to Israel, some to one specific person, some to the church directly — and treating them all the same produces confusion, not faith.

So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it. (Isaiah 55:11)

Notice the phrase “the thing whereto I sent it.” A promise is sent to accomplish something specific, for someone specific. Reading it rightly means asking who it was sent to before asking whether it was sent to you.

That’s the same rightly-dividing question from a moment ago, aimed at one verse at a time. Who is speaking, who is being addressed, and what has already been fulfilled all change what a promise means for your life today.

How Do the Word of God and the Cross Work Together?

The Word and the Cross are never separate in God’s economy. The entire Bible, from Genesis to Revelation, points to one event.

For I determined not to know any thing among you, save Jesus Christ, and him crucified. (1 Corinthians 2:2)

The Cross is where every promise in Scripture is grounded. Faith in Christ and Him crucified is what gives the Holy Spirit room to apply the Word to your actual life.

Without the Cross as the object of your faith, the Bible becomes a book of rules to keep, and rules only get you so far. Faith in what Jesus already did is what turns those same pages into something the Spirit can actually work through.
