He who has knowledge restrains and is careful with his words,
And a man of understanding and wisdom has a cool spirit (self-control, an even temper). Proverbs 17:27
A cool spirit is one that is not soon angry, calm, sedate, and not easily provoked to wrath: the “Keri”, or marginal reading, is “of an excellent” or “precious spirit” (f); and such a one is a right spirit; a spirit of faith and love, and of a sound mind; and of such a spirit is a man of understanding in things divine and spiritual; to have a spirit of prayer, and to be tender-hearted, and of a sympathizing and forgiving spirit, is to be of an excellent spirit. The Targum is, “humble in spirit;” and a meek and quiet spirit is in the sight of God of great price; the Lord has a great regard to such who are of a humble and contrite spirit: with these he dwells, to these he gives more grace; these are like to Christ, and have the fruits of his Spirit, and are very useful and ornamental. The Septuagint, Syriac, and Arabic versions render it, “patient” or “longsuffering”; and to be of a patient spirit is to be of an excellent spirit: such bear afflictions and reproaches quietly; wait God’s own time for hearing and helping them, and live in the comfortable expectation of heaven and happiness; and such show themselves to be wise and understanding men. – Gill’s Exposition
I want to be someone who exhibits knowledge and understanding in my interactions with people. Self-control is crucial and only possible by the person and work of the Holy Spirit. Of course, this means that I must submit to his work. Pride must be cast aside. The old me needs to be told no again and again and again. He refuses to die even though the death-blow has been administered by Christ’s work on the cross. In Christ, I am capable of restraining my words and exhibiting a cool spirit.
Yet we do speak wisdom among those spiritually mature [believers who have teachable hearts and a greater understanding]; but [it is a higher] wisdom not [the wisdom] of this present age nor of the rulers and leaders of this age, who are passing away; but we speak God’s wisdom in a mystery, the wisdom once hidden [from man, but now revealed to us by God, that wisdom] which God predestined before the ages to our glory [to lift us into the glory of His presence]. None of the rulers of this age recognized and understood this wisdom; for if they had, they would not have crucified the Lord of glory; but just as it is written [in Scripture],
“Things which the eye has not seen and the ear has not heard,
And which have not entered the heart of man,
All that God has prepared for those who love Him [who hold Him in affectionate reverence, who obey Him, and who gratefully recognize the benefits that He has bestowed].”
For God has unveiled them and revealed them to us through the [Holy] Spirit; for the Spirit searches all things [diligently], even [sounding and measuring] the [profound] depths of God [the divine counsels and things far beyond human understanding]. For what person knows the thoughts and motives of a man except the man’s spirit within him? So also no one knows the thoughts of God except the Spirit of God. Now we have received, not the spirit of the world, but the [Holy] Spirit who is from God, so that we may know and understand the [wonderful] things freely given to us by God. We also speak of these things, not in words taught or supplied by human wisdom, but in those taught by the Spirit, combining and interpreting spiritual thoughts with spiritual words [for those being guided by the Holy Spirit].
But the natural [unbelieving] man does not accept the things [the teachings and revelations] of the Spirit of God, for they are foolishness [absurd and illogical] to him; and he is incapable of understanding them, because they are spiritually discerned and appreciated, [and he is unqualified to judge spiritual matters]. But the spiritual man [the spiritually mature Christian] judges all things [questions, examines and applies what the Holy Spirit reveals], yet is himself judged by no one [the unbeliever cannot judge and understand the believer’s spiritual nature]. For who has known the mind and purposes of the Lord, so as to instruct Him? But we have the mind of Christ [to be guided by His thoughts and purposes]. – 1 Corinthians 2:6-16
