¹⁴ But you must ^(A)continue in the things which you have learned and been assured of, knowing from whom you have learned them, ¹⁵ and that from childhood you have known ^(B)the Holy Scriptures, which are able to make you wise for salvation through faith which is in Christ Jesus.

^16 (C)All Scripture is given by inspiration of God, ^(D)and is profitable for doctrine, for reproof, for correction, for ^[a]instruction in righteousness, ^17 (E)that the man of God may be complete, ^(F)thoroughly equipped for every good work.

^4 (A)No one engaged in warfare entangles himself with the affairs of this life, that he may please him who enlisted him as a soldier. ⁵ And also ^(B)if anyone competes in athletics, he is not crowned unless he competes according to the rules.

⁹ Now I rejoice, not that you were made sorry, but that your sorrow led to repentance. For you were made sorry in a godly manner, that you might suffer loss from us in nothing. ¹⁰ For ^(A)godly sorrow produces repentance leading to salvation, not to be regretted; ^(B)but the sorrow of the world produces death. ¹¹ For observe this very thing, that you sorrowed in a godly manner: What diligence it produced in you, what ^(C)clearing of yourselves, what indignation, what fear, what vehement desire, what zeal, what vindication! In all things you proved yourselves to be ^(D)clear in this matter.

^2 (A)You are our epistle written in our hearts, known and read by all men; ³ clearly you are an epistle of Christ, ^(B)ministered by us, written not with ink but by the Spirit of the living God, not ^(C)on tablets of stone but ^(D)on tablets of flesh, that is, of the heart.
