The source of heavenly wisdom is from above, from the throne of the Holy God, which God grants to His children abiding in Him. Its characteristics are:
A) Pure: that is, straight forward and bestows on its owner a pure heart and a chaste life. As God is pure (1 John 3:3), and His words are pure, therefore, whoever obtains God’s wisdom cannot tolerate evil but is drawn to the pure life resembling God.
B) Peaceable: that is, full of peace, for it is written that all its ways are peaceable. By wisdom, one is drawn toward God, and his heart is filled with peace and he pours outer peace on others, for he cannot tolerate to see fights or loud voices. He obeys the commandment, “Therefore let us pursue the things which make for peace and the things by which one may edify another.” [Rom 14:19]
C) Gentle: When the heart is filled with peace toward others and does for the edification of others, he is gentle toward the shortcomings and weaknesses of others, and he focuses on how to win many to Christ. This gentleness is not an outer appearance but an inner life, whether one talks or is silent, one is chastened or criticized. In all that, he is gentle and compassionate, but in strictness.
D) Willing to yield: that is obedient. This is the work of God’s wisdom to grant us submission to Him and to His word, so we may not work by our own will but by the will of God.
E) Full of mercy and good fruits: Where there is obedience, there has to be good fruits. As false wisdom drives us to pride then to evil works [Verse 16], so true wisdom is practical for it drives us to obedience, submission, mercy and good fruits.
As faith without works is dead, so wisdom without fruits is fake. The book of Wisdom described it that it is ready for every good deed and the love of humanity. The wisdom of God Incarnate declares this to us when “He went about doing good...” [Acts 10:38]
So let us put on the Lord Jesus, the true Wisdom, so we may bring forth many fruits, [John 5:15], and go with Him doing well.
• This is the wisdom, which tames the tongue, descending from above, not springing from the human heart. Would anyone dare to snatch it away from the grace of God and, with overweening pride, place it in the power of man? (1)
St. Augustine
F) Without Partiality: that is, steadfast and not shaken nor divided. It has one clear goal, which is to clearly reveal the heavenly road, in spite of all the difficulties and hardships.
True wisdom makes one unable to tolerate having a divided heart between the love of God and the love of the world, nor to falter between the eternal and the temporal matters, nor to mix between trusting God and trusting the human nature. The heart is steadfast in his love, hope, and direction. It also means not to favor the rich over the poor.
G) Without hypocrisy: that is, it does not carry what is on the outside things different than what is on the inside. The apostle said, “we conducted ourselves in the world in simplicity and godly sincerity, not with fleshly wisdom but by the grace of God, and more abundantly toward you.” [2Cor 1:12]
The Lord Jesus warned His disciples from the leaven of the Pharisees, which is their hypocrisy.
H) “The fruit of righteousness is sown in peace by those who make peace”: for through wisdom, one reaps the fruits of righteousness. This harvest full of security is the fruit of sowing peace, meaning that through wisdom, one makes peace and reaps the fruits of righteousness.
He sows peace by his submission to the Spirit of God and not resisting Him. He reaps righteousness, and this is the fruit of the Spirit to whom he submitted and obeyed and responded to His work persistently.
• You shall rejoice in the morning, that is, in the world to come, if you have gathered the fruits of righteousness by weeping and labor in this world (2).
