But evil men and impostors will grow worse and worse, deceiving and being deceived. But you must continue in the things which you have learned and been assured of, knowing from whom you have learned them, and that from childhood you have known the Holy Scriptures, which are able to make you wise for salvation through faith which is in Christ Jesus. All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work.
The only way to defeat Satan's lies is with God's truth. "Thus saith the Lord!" is the final answer to every question. Evil men and deceivers are going to get worse and worse. They will deceive more and more. Why? Because they are being deceived by Satan! In these last days, there will be more deception and imitation; and the only way a believer will be able to tell the true from the false is by knowing the Word of God. Timothy had been taught the Word of God from the time he was a child; his grandmother and mother had faithfully taught him the Old Testament Scriptures. Timothy was to continue in what he had been taught. We never outgrow the Word of God.
In the text of 2 Timothy chapter 3, Paul made some important statements about the Scriptures:
a) They are the Holy Scriptures (v. 15a). "The sacred letters" is a literal translation. The word for holy means "consecrated for sacred use." The Bible is different from every other book, even books about the Bible, because it has been set apart by God for special sacred uses. We must treat the Bible as the special book it is. The way we treat the Bible shows others how much or how little we respect it. Paul gives us the right attitude toward the Word of God (1 Thessalonians 2:13).
b) The Scriptures lead us to salvation (v. 15b). We are not saved by believing the Bible (John 5:39), but by trusting the Christ who is revealed in the Bible. Timothy was raised on the Holy Scriptures in a godly home. Yet it was not until Paul led him to Christ that he was saved. What is the relationship of the Bible to salvation? To begin with, the Bible reveals our need for salvation. It is a mirror that shows us how filthy we are in God's sight. The Bible explains that every lost sinner is condemned now (John 3:18-21) and needs a Saviour now. It also makes it clear that a lost sinner cannot save their self. But the Bible also reveals God's wonderful plan of salvation: Christ died for our sins! If we trust Him, He will save us (John 3:16-18). The Bible also helps give us the assurance of our salvation (1 John 5:9-13). Then the Bible becomes our spiritual food to nourish us that we might grow in grace and serve Christ. The Word of God is our sword for fighting Satan, and overcoming temptation.
c) The Scriptures are true and dependable (v. 16a). "All Scripture is God-breathed.” The doctrine of the inspiration of Scripture is vitally important, and a doctrine that Satan has attacked from the beginning ("Yea, hath God said?" (Genesis 3:1). It is inconceivable that God would give His people a book they could not trust. He is the God of truth (Deuteronomy 32:4); Jesus is "the truth" (John 14:6); and the "Spirit is truth" (1 John 5:6). Jesus said of the Scriptures, "Thy Word is truth" (John 17:17). The Holy Spirit of God used men of God to write the Word of God (2 Peter 1:20-21). The Spirit did not erase the natural characteristics of the writers. In fact, God in His providence prepared the writers for the task of writing the Scriptures. Each writer has his own distinctive style and vocabulary. Each book of the Bible grew out of a special set of circumstances. In His preparation of men, in His guiding of history, and in His working through the Spirit, God brought about the miracle of the Scriptures.
We must not think of "inspiration" the way the world thinks when it says, "Shakespeare was certainly an inspired writer." What we mean by biblical inspiration is the supernatural influence of the Holy Spirit on the Bible's writers, which guaranteed that what they wrote was accurate and trustworthy. Revelation means the communicating of truth to man by God; inspiration has to do with the recording of this communication in a way that is dependable. Whatever the Bible says about itself, man, God, life, death, history, science, and every other subject is true. This does not mean that every statement in the Bible is true, because the Bible records the lies of men and of Satan. But the record is true.
e) The Scriptures are profitable (v. 16b). They are profitable for doctrine (what is right), for reproof (what is not right), for correction (how to get right), and for instruction in righteousness (how to stay right). A Christian who studies the Bible and applies what he or she learns will grow in holiness, and avoid many pitfalls in this world.
f) The Scriptures equip us for service (v. 17). Paul called Timothy a "man of God" (1 Timothy 6:11); but here Paul states that any Christian can become a person "of God." How? By studying the Word of God, obeying it, and letting it control his or her life. It is worth noting that all of the "men of God" named in Scripture, including Moses, Samuel, Elijah, Elisha, David, and Timothy, were men who were devoted to God's Word. Two words in this verse are especially important: "perfect" and "furnished." The word translated "perfect" means "complete, in fit shape, in fit condition." It does not begin to suggest sinless perfection. Rather, it implies being fitted for use. "Furnished" has a similar meaning: "equipped for service." The Word of God furnishes, and equips a believer so that he or she can live a life that pleases God and do the work God wants them to do. The better we know the Word, the better we are able to live, and work for God.
The purpose of Bible study is not just to understand doctrines or to be able to defend the faith, as important as these things are. The ultimate purpose is the equipping of the believers who read it. It is the Word of God that equips God's people to do the work of God. The times are not going to get better, but we Christians can become better people, even in bad times. We must separate ourselves from that which is false, devote ourselves to that which is true, and continue in our study of the Word of God.
