God’s word is useful, I’ve mentioned one of my favorite verses is:
Pro 26:1 As snow in summer, and as rain in harvest, so honour is not seemly for a fool.
Pro 26:3 A whip for the horse, a bridle for the ass, and a rod for the fool‘s back.
Pro 26:4 Answer not a fool according to his folly, lest thou also be like unto him.
Pro 26:5 Answer a fool according to his folly, lest he be wise in his own conceit.
Pro 26:6 He that sendeth a message by the hand of a fool cutteth off the feet, and drinketh damage.
Pro 26:7 The legs of the lame are not equal: so is a parable in the mouth of fools.
Pro 26:8 As he that bindeth a stone in a sling, so is he that giveth honour to a fool.
Pro 26:9 As a thorn goeth up into the hand of a drunkard, so is a parable in the mouth of fools.
Pro 26:10 The great God that formed all things both rewardeth the fool, and rewardeth transgressors.
Pro 26:11 As a dog returneth to his vomit, so a fool returneth to his folly.
Pro 26:12 Seest thou a man wise in his own conceit? there is more hope of a fool than of him.
We could find no better place to start than with the riches of God’s own words in the Bible.
Psa 19:7 The law of the LORD is perfect, converting the soul: the testimony of the LORD is sure, making wise the simple.
Psa 19:8 The statutes of the LORD are right, rejoicing the heart: the commandment of the LORD is pure, enlightening the eyes.
Psa 19:9 The fear of the LORD is clean, enduring for ever: the judgments of the LORD are true and righteous altogether.
Psa 19:10 More to be desired are they than gold, yea, than much fine gold: sweeter also than honey and the honeycomb.
Of course if one rejects God first then one does not need to follow his law.
Psa 14:1 To the chief Musician, A Psalm of David. The fool hath said in his heart, There is no God. They are corrupt, they have done abominable works, there is none that doeth good.
Psa 53:1 To the chief Musician upon Mahalath, Maschil, A Psalm of David. The fool hath said in his heart, There is no God. Corrupt are they, and have done abominable iniquity: there is none that doeth good.
And just for good measure, Jesus and Paul make these connections….not the little word “all”.
Mat 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
Mat 28:20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
All Scripture Is Breathed Out by God
2Ti 3:10 But thou hast fully known my doctrine, manner of life, purpose, faith, longsuffering, charity, patience,
2Ti 3:11 Persecutions, afflictions, which came unto me at Antioch, at Iconium, at Lystra; what persecutions I endured: but out of them all the Lord delivered me.
2Ti 3:12 Yea, and all that will live godly in Christ Jesus shall suffer persecution.
2Ti 3:13 But evil men and seducers shall wax worse and worse, deceiving, and being deceived.
2Ti 3:14 But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them;
2Ti 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
2Ti 3:17 That the man of God may be perfect, throughly furnished unto all good works.
