“All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness” – 2 Timothy 3:16
Pastors and Theologians refer to the term the “sufficiency of scripture” to mean that the bible is the only book we need. There are some issues that any attempt to reason or appeal to something outside of the bible is meant with charges of denying the “sufficiency of scripture.” But is this what the verse means? If you were sick and went to the doctor and he said he wasn’t sure what was wrong but let me read Exodus to see if that helps, would this instill confidence? If you take your car into a mechanic for brake issues and he opened his bible to Isaiah 26:4 and told you, “You don’t need me to fix your breaks cause Isaiah 26:4 says trust in the Lord always, you’ll be fine” is it a denial of scripture to take your business elsewhere?
Paul has been speaking to Timothy about what he needs to know to preserve in ministry. Part of what Timothy needs is to rely on scripture because they are “able to make you wise for salvation through faith in Christ Jesus.” We cannot forget the context of Paul’s letter. When he was speaking to Timothy, he was not speaking about diagnosing illnesses or fixing cars. What scripture is “sufficient” for needs to be put into the proper context to be understood. Yes, scripture has theological principles that can apply and council a whole host of issues, but if we are to “rightly divide” the word then we must have a correct view of what it means to say that in all things “scriptures are sufficient”
