Second in a series of studies of 2 Timothy 3:14-17
“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” (2 Timothy 3:16-17).
In this context, “Scripture” refers to the Old Testament, although the same point applies to the New Testament. “Inspiration” means God dictated the words He wanted the writers to record, the same words that made Timothy “wise to salvation.”
“Doctrine” means teaching or instruction. So, if one wants to please God, he must take heed to teaching found in the scriptures because they will provide a spiritual benefit. The Old Testament teaches us about God and His expectations for mankind. The New Testament provides instruction about the practices God wants His children to follow under the new system.
And that is exactly the point Paul emphasizes to the young preacher here: Timothy was to teach that the scriptures came directly from God, and believers of all ages must listen to them to receive the spiritual benefits desired.
