For length of days and years of a life [worth living] and tranquility [inward and outward and continuing through old age till death], these shall they add to you. Let not mercy and kindness [shutting out all hatred and selfishness] and truth [shutting out all deliberate hypocrisy or falsehood] forsake you; bind them about your neck, write them upon the tablet of your heart. So shall you find favor, good understanding, and high esteem in the sight [or judgment] of God and man. Lean on, trust in, and be confident in the Lord with all your heart and mind and do not rely on your own insight or understanding. In all your ways know, recognize, and acknowledge Him, and He will direct and make straight and plain your paths. (Proverbs 3:2-6 AMP)
MY SON, if you will receive my words and treasure up my commandments within you, Making your ear attentive to skillful and godly Wisdom and inclining and directing your heart and mind to understanding [applying all your powers to the quest for it]; Yes, if you cry out for insight and raise your voice for understanding, If you seek [Wisdom] as for silver and search for skillful and godly Wisdom as for hidden treasures, Then you will understand the reverent and worshipful fear of the Lord and find the knowledge of [our omniscient] God. For the Lord gives skillful and godly Wisdom; from His mouth come knowledge and understanding. He hides away sound and godly Wisdom and stores it for the righteous (those who are upright and in right standing with Him); He is a shield to those who walk uprightly and in integrity, That He may guard the paths of justice; yes, He preserves the way of His saints. Then you will understand righteousness, justice, and fair dealing [in every area and relation]; yes, you will understand every good path. For skillful and godly Wisdom shall enter into your heart, and knowledge shall be pleasant to you. Discretion shall watch over you, understanding shall keep you, (Proverbs 2:1-11 AMP)
dictionary definition of discretion begins with “the quality of being discreet.” And to be discreet means to be “wise or judicious in avoiding mistakes or faults; prudent; circumspect; cautious; not rash.” In other words, discretion is exercising judgment tempered with these attributes in order to arrive at a final decision or outcome.
Prudence means “cautious, practical wisdom; good judgment; discretion; exercising caution in preparing for the future in a judicious manner.” (Take time to look up the word judicious, as well.) Notice that the definitions of these terms are virtually the same, and that they are defined in terms of each other.
