Colossians 3:15-17 KJV

“So that thou incline thine ear unto wisdom, And apply thine heart to understanding; Yea, if thou criest after knowledge, And liftest up thy voice for understanding; If thou seekest her as silver, And searchest for her as for hid treasures; Then shalt thou understand the fear of the LORD, And find the knowledge of God. For the LORD giveth wisdom: Out of his mouth cometh knowledge and understanding. He layeth up sound wisdom for the righteous: He is a buckler to them that walk uprightly. He keepeth the paths of judgment, And preserveth the way of his saints. Then shalt thou understand righteousness, and judgment, And equity; yea, every good path. When wisdom entereth into thine heart, And knowledge is pleasant unto thy soul; Discretion shall preserve thee, Understanding shall keep thee: To deliver thee from the way of the evil man, From the man that speaketh froward things;”

Proverbs 2:2-12 KJV

Proverbs 14:29-30 KJV

“Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God. Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual. But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned. But he that is spiritual judgeth all things, yet he himself is judged of no man. For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ.”

My little children, let us not love in word, neither in tongue; but in deed and in truth.”
