2 Timothy 3:16

Inspiration of God; God directed the men who wrote it what to write, and how to write it, that as a rule of faith and practice for men it might be perfect.

For doctrine; the communication of instruction.

For reproof; to show men their sins.

For correction; to reclaim them.

For instruction; in what is right, and the presentation of the highest and best motives to induce men to do it. As all Scripture is given by inspiration of God, and like its author is perfect, and as it tends to make perfect all who believe and obey it, it should with the least possible delay be put into the hands of all people.
