II Corinthians 4:2

Thy word is very pure: therefore thy servant loveth it.—The statutes of the Lord are right, rejoicing the heart: the commandment of the Lord is pure, enlightening the eyes.—Every word of God is pure: he is a shield unto them that put their trust in him. Add thou not unto his words, lest he reprove thee, and thou be found a liar.

Thy word have I hid in mine heart, that I might not sin against thee. I will meditate in thy precepts, and have respect unto thy ways.—Brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report, if there be any virtue, and if there be any praise, think on these things.—As newborn babes, desire the sincere milk of the word that ye may grow thereby.

Have you "renounced the hidden things of dishonesty" - the things that your sense of honour will not allow to come to the light? You can easily hide them. Is there a thought in your heart about anyone which you would not like to be dragged into the light? Renounce it as soon as it springs up; renounce the whole thing until there is no hidden thing of dishonesty or craftiness about you.

Envy, jealousy, strife - these things arise not necessarily from the disposition of sin, but from the make-up of your body which was used for this kind of thing in days gone by (see Romans 6:19 and 1 Peter 4:1-2). Maintain a continual watchfulness so that nothing of which you would be ashamed arises in your life.
