Jer. 2:19 "Thine own wickedness shall correct thee, and thy backslidings shall reprove thee: know therefore and see that it is an evil thing and bitter, that thou hast forsaken the LORD thy God, and that my fear is not in thee, saith the Lord GOD of hosts."

Prov. 1:28-29 "Then shall they call upon me, but I will not answer; they shall seek me early, but they shall not find me: For that they hated knowledge, and did not choose the fear of the LORD:"

Prov. 14:2 "He that walketh in his uprightness feareth the LORD: but he that is perverse in his ways despiseth him."

Rom. 3:10-18 "As it is written, There is none righteous, no, not one: There is none that understandeth, there is none that seeketh after God. They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one. Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips: Whose mouth is full of cursing and bitterness: Their feet are swift to shed blood: Destruction and misery are in their ways: And the way of peace have they not known: There is no fear of God before their eyes."

3) There are many benefits to fearing God.

Psa. 128:1 "Blessed is every one that feareth the LORD; that walketh in his ways."

Psa. 25:14 "The secret of the LORD is with them that fear him; and he will shew them his covenant."

Psa. 33:18 "Behold, the eye of the LORD is upon them that fear him, upon them that hope in his mercy;"

Psa. 34:7 "The angel of the LORD encampeth round about them that fear him, and delivereth them."

Psa. 34:9 "O fear the LORD, ye his saints: for there is no want to them that fear him."

Psa. 103:13 "Like as a father pitieth his children, so the LORD pitieth them that fear him."

Psa. 115:11 "Ye that fear the LORD, trust in the LORD: he is their help and their shield."

Psa. 115:13 "He will bless them that fear the LORD, both small and great."

Psa. 128:4 "Behold, that thus shall the man be blessed that feareth the LORD."

Psa. 147:11 "The LORD taketh pleasure in them that fear him, in those that hope in his mercy."

Prov. 10:27 "The fear of the LORD prolongeth days: but the years of the wicked shall be shortened."

Prov. 15:16 "Better is little with the fear of the LORD than great treasure and trouble therewith."

Prov. 19:23 "The fear of the LORD tendeth to life: and he that hath it shall abide satisfied; he shall not be visited with evil."

Prov. 31:30 "Favour is deceitful, and beauty is vain: but a woman that feareth the LORD, she shall be praised."

4) Fear is the beginning of wisdom. Without it you cannot get saved, and without it you'll never be able to stop falling into sin. 

Prov. 2:5 "Then shalt thou understand the fear of the LORD, and find the knowledge of God."

Prov. 14:27 "The fear of the LORD is a fountain of life, to depart from the snares of death."

Psa. 111:10 "The fear of the LORD is the beginning of wisdom: a good understanding have all they that do his commandments: his praise endureth for ever."

(also see Prov. 1:7, 9:10, 15:33)

Prov. 3:7 "Be not wise in thine own eyes: fear the LORD, and depart from evil."

Prov. 16:6 "By mercy and truth iniquity is purged: and by the fear of the LORD men depart from evil."

How can you learn to fear God more?

Prov. 2:1-5 "My son, if thou wilt receive my words, and hide my commandments with thee; 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."

Remembering these two verses also helps generate some fear of God:

Num. 32:23 "But if ye will not do so, behold, ye have sinned against the LORD: and be sure your sin will find you out."

Gal. 6:7 "Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap."

The role fear plays in salvation:

Acts :13:26 "Men and brethren, children of the stock of Abraham, and whosoever among you feareth God, to you is the word of this salvation sent."

Phil. 2:12 "Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling."

Psa. 9:20 "Put them in fear, O LORD: that the nations may know themselves to be but men. Selah."

Luke 12:1-5 "In the mean time, when there were gathered together an innumerable multitude of people, insomuch that they trode one upon another, he began to say unto his disciples first of all, Beware ye of the leaven of the Pharisees, which is hypocrisy. For there is nothing covered, that shall not be revealed; neither hid, that shall not be known. Therefore whatsoever ye have spoken in darkness shall be heard in the light; and that which ye have spoken in the ear in closets shall be proclaimed upon the housetops. And I say unto you my friends, Be not afraid of them that kill the body, and after that have no more that they can do. But I will forewarn you whom ye shall fear: Fear him, which after he hath killed hath power to cast into hell; yea, I say unto you, Fear him."

Heb. 10:29-31 "Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace? For we know him that hath said, Vengeance belongeth unto me, I will recompense, saith the Lord. And again, The Lord shall judge his people. It is a fearful thing to fall into the hands of the living God."
