This is all I need.
2 Timothy 3:16-17 (NASB)
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.
Is scripture is inspired by God, why do I need a man to tell me something different or add to something there?
This is an excellent question, solarguy17 and I think gets at the heart of the thread topic.
I think first it is important to look at what this verse actually is saying. I find that it is often misunderstood by those reading it. You are right, it says that scripture is inspired. Coming from God as it does it is “profitable”, and in some translations “useful”. This verse does NOT say we don’t need anything else, or that Scripture is the be all and end all of God’s revelation to man.
Next we look at what type of activities in which Scripture is profitable (useful). These activities include teaching, reproof, correction and training in rightousness. These are all parts of the Christian process of sanctification. What is the goal of all this teaching, reproving, correcting and training? That the man of God may be equipped. Scripture is useful in equipping the tasks of forming disciples.
Nowhere does it say that Scripture alone accomplishes these tasks. In fact, we find the contrary. To whom did God give these tasks?
Eph 4:10-14
10 He who descended is the same one who ascended far above all the heavens, so that he might fill all things.) 11
The gifts he gave were that some would be apostles, some prophets, some evangelists, some pastors and teachers, 12 to equip the saints for the work of ministry, for building up the body of Christ, 13 until all of us come to the unity of the faith and of the knowledge of the Son of God, to maturity, to the measure of the full stature of Christ.
Jesus gave the gift of teaching and pastoring to PEOPLE, and these PEOPLE are charged with the responsibilty to equip the saints for the work of the ministry. These PEOPLE find scripture useful/profitable in the tasks of equiping the saints.
So I think that St. Paul here answers your question clearly. You need the people appointed and gifted by Jesus to equip you for the work of the ministry. You need to benefit from their use of the Scripture as they reprove, correct and teach you according to the gifts that God has established. And in the next verses he concludes:
Eph 4:14-16
We must no longer be children, tossed to and fro and blown about by every wind of doctrine, by people’s trickery, by their craftiness in deceitful scheming. 15 But speaking the truth in love, we must grow up in every way into him who is the head, into Christ, 16 from whom the **whole body, joined and knit together by every ligament with which it is equipped, as each part is working properly, promotes the body’s growth in building itself up in love. **
You need it because Jesus established His Church, and He is buildign that Church in love. He provided the gifted people to profitably use the scriptures for the purpose of bringing us all to maturity.
You need those people because that is the way Jesus set it up. It is His church, so He gets to decide what you need, and how you are going to get your need met.
