2 Timothy 3:16

¹⁴ But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them;

¹⁵ And that from a child thou hast known the holy scriptures, which are able to make thee wise unto 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:

¹⁷ That the man of God may be perfect, throughly furnished unto all good works.

Do read the surrounding verses too, because the context often says more than a single verse.
