There are a number of good reasons why one should study the Bible. First, one should study it because it is inspired of God (see article, “Is the Bible God’s Inspired Word?”). Because it is inspired, the message is truth and everything it says is true. For instance, the Bible says that “all have sinned and come short of the glory of God” (Rom.3:23) and if we refuse to seek salvation for those sins, the Bible tells us that we will be judged by the Word of God, “He who rejects Me and does not receive My sayings, has one who judges him; the word I spoke is what will judge him at the last day.” (Jn.12:48)
A study of the Word of God can show us how to be saved (James 1:21) (see article “What Must I do To Be Saved?”) and thus prepare us for the judgment at which time saved people will hear God say, “Come, you who are blessed of My Father, inherit the kingdom prepared for you from the foundation of the world.” (Matt.25:34)
A study of the Bible will open up to us everything that has to do with life and godliness (II Peter 1:3). The great treasure house of information that is in the Bible deals with all aspects of life and teaches us how to conduct ourselves in all the relationships of life. Also, Paul told the Ephesian church that they could understand or have insight into the mystery of Christ, by reading what he wrote and so can we. (Eph.3:1-5)
A study of the Bible will tell us how to have the best kind of life here on earth, “for bodily discipline is only of little profit, but godliness is profitable for all things, since it holds promise for the present life and also for the life to come.” (I Timothy 4:8)
A study of the Bible will show us all the commands of God that we need to obey. Jesus told the apostles to “teach them all things that I have commanded you” referring to those who had been made disciples of Jesus. (Matthew 28:18-20)
A study of the Bible will tell us of all the blessings that God has for us. Paul tells us that “all spiritual blessings are in Christ Jesus” (Eph.1:3) and Jesus said He came to give us life more abundantly (John 10:10). Some of these blessings include a happy and contented life here as the fruit of the Spirit is produced in our lives (love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control).
A study of the Bible helps us to learn from the mistakes of others. The Old Testament especially is full of examples of this. I Corinthians 10:11 says, “Now these things happened to them as an example, and they were written for our instruction, upon whom the ends of the ages have come.” The study of Ecclesiastes is a whole book that helps us learn from the experiences of Solomon, King of Israel as he details his frustration is seeking to learn the meaning of life and fulfillment and purpose. His conclusion is “The whole purpose of man is to fear God and keep His commandments.” (Ecclesiastes 12:13,14)
These are just a few of the reasons why one should study the Bible. And all of the above reasons are summed up in this one reason- in the Bible we learn about God’s love. (John 3:16)
And we learn how we can express our love to God, “but whoever keeps His word, in him the love of God has truly been perfected.” ( I John 2:5)
It is truly worth it to spend time in studying the Bible. “Study to show thyself approved to God, a workmen that needs not to be ashamed, rightly dividing the word of truth.” II Timothy 2:15
For a fuller perspective on this topic, we would suggest that you read the entire Psalms 119 which gives many other reasons for studying the Bible.
