Proverbs 9:9-10 (ESV)
Give instruction to a wise man, and he will be still wiser; teach a righteous man, and he will increase in learning. The fear of the Lord is the beginning of wisdom, and the knowledge of the Holy One is insight.
Philippians 1:9-10a
This is my prayer: that your love may abound more and more in knowledge and depth of insight, so that you may be able to discern what is best and may be pure and blameless for the day of Christ.
Titus 1:1b
Knowledge of the truth...leads to godliness
James 3:13-17 (ESV)
Who is wise and understanding among you? By his good conduct let him show his works in the meekness of wisdom. But if you have bitter jealousy and selfish ambition in your hearts, do not boast and be false to the truth. This is not the wisdom that comes down from above, but is earthly, unspiritual, demonic. For where jealousy and selfish ambition exist, there will be disorder and every vile practice. But the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy and good fruits, impartial and sincere.
C.H. Spurgeon
Wisdom is the right use of knowledge. To know is not to be wise. Many men know a great deal, and are all the greater fools for it. There is no fool so great a fool as a knowing fool. But to know how to use knowledge is to have wisdom.
A.W. Tozer The Divine Conquest
The inadequacy of much of our spiritual experience be traced back to our habit of skipping through the corridors of the Kingdom like children through the marketplace, chattering about everything, but pausing to learn the true value of nothing.
J.I. Packer
Not until we have become humble and teachable, standing in awe of God's holiness and sovereignty... acknowledging our own littleness, distrusting our own thoughts, and willing to have our minds turned upside down, can divine wisdom become ours.
CAUTION
A.W. Pink on evangelistic and Biblical counseling discernment, in “Assurance”
https://gracegems.org/Pink/assurance.htm
If (the servant of God) is to faithfully deal with souls, he must address himself to the condition they are in. Unless he is much upon his guard, unless he constantly seeks wisdom and guidance from above — he is likely to make bad matters worse.
The truth of eternal punishment should be faithfully preached by every servant of God — but would a broken-hearted woman, who had just lost her husband or child, be a suitable audience?
The glory and bliss of the heavenly state is a precious theme — but would it be fitting to present it unto a professing Christian who was intoxicated?
The eternal security of the saints is clearly revealed in Holy Writ, but does that justify me pressing it on the attention of a backslidden child of God?
