Is fear of hell a good reason to be saved?

from the old testament

• Scripture teaches that “the fear of the LORD is the beginning of wisdom” (Proverbs 9:10a). Fearing God includes revering Him and what He says. Solomon wrote, “The end of the matter; all has been heard. Fear God and keep his commandments, for this is the whole duty of man. For God will bring every deed into judgment, with every secret thing, whether good or evil” (Ecclesiastes 12:13–14). In short, fearing God is spiritually healthy and keeps us humble.
• Scripture is filled with examples of God’s wrath and destruction of sinners. The flood account, however, is perhaps the most sweeping judgment until Jesus returns for the final judgment (Genesis 6—7). Other major examples of judgment include the destruction of Sodom and Gomorrah (Genesis 19) and the death of all of Egypt's firstborn (Exodus 12:29–30). These and other acts are reminders of God’s justice and judgment. While we may fear God's judgment, it is a starting point in understanding God.
• As God was about to judge Israel, He gave them a warning to fear His judgment, encouraging them to repent: “Repent and turn from all your transgressions, lest iniquity be your ruin. Cast away from you all the transgressions that you have committed, and make yourselves a new heart and a new spirit! Why will you die, O house of Israel?” (Ezekiel 18:30–31; cf. Joel 2:12–13). The threat of death was given as a motivator to start obeying.
• Other examples show that fear can lead to repentance, which can lead to salvation. For example, Jonah was sent to Nineveh to tell them that God was going to destroy them in forty days. The nation repented because of that warning. After that, "God saw what they did, how they turned from their evil way, [and] God relented of the disaster that he had said he would do to them, and he did not do it” (Jonah 3:10). God wants the best for His children, which means to come to Him in repentance. Sometimes fear gets our attention.

from the new testament

• Jesus spoke about God’s coming judgment to motivate people to repent: “Do not fear those who kill the body but cannot kill the soul. Rather fear him who can destroy both soul and body in hell” (Matthew 10:28).
• Jesus also taught to fear hell so much that one would go to extremes to avoid it. Using hyperbole, He said, “If your hand causes you to sin, cut it off. It is better for you to enter life crippled than with two hands to go to hell, to the unquenchable fire. And if your foot causes you to sin, cut it off. It is better for you to enter life lame than with two feet to be thrown into hell. And if your eye causes you to sin, tear it out. It is better for you to enter the kingdom of God with one eye than with two eyes to be thrown into hell” (Mark 9:43–47). His point was that nothing on Earth is worth losing eternal salvation.
• God is loving, which is why He offers us salvation as a free gift. But some recognize His love and ignore His justice, which has eternal consequences (Hebrews 10:26–27, 31).
• Fear also motivates us to share the gospel. Paul said, “knowing the fear of the Lord, we persuade others” (2 Corinthians 5:11). The good news is that when one is truly saved, fear of judgment is gone forever (1 John 4:18).
• But fearing it is not the same as desiring to be righteous. James noted that “even the demons believe [in God]—and shudder” (James 2:19). But their fear does not lead to repentance. Salvation is not merely a “get out of hell free” card. Fully committing to Christ leads to salvation and is the mark of spiritual maturity. Some profess faith out of fear of judgment without truly submitting to Christ, and Jesus warns about this (Matthew 7:21–23).
• True sorrow over sin involves repenting of sin and trusting in Jesus as Lord and Savior (2 Corinthians 7:10; Romans 10:9–10; Acts 16:31; John 3:16).

implications for today

Hell is being separated from God. It's being separated from all that is good like His love and mercy. It is a life of conscious torment. Unrepentant sinners actualize that choice to be away from God's love and under His wrath for eternity. When considered like this, it would be foolish not to consider that and look for a Savior from it.

Fear is a real motivator sometimes. However, only fear that leads us to repentance and trusting in Jesus Christ's death and resurrection provides us with salvation. Faith, though it can be motivated by fear, is what saves us from sin and the punishment we deserve.

We should allow fear to help us see just how much God hates sin. As we start to understand our sin, we will see that we have no way to “pay God back” for what we have done. There is but one option: stop, repent, and believe in Jesus (Romans 10:9–10).

But Proverbs 9:10a says, "The fear of God is the beginning of wisdom" (emphasis added). It isn't the end. We continue to grow, learn, and seek God on the basis of love, not just fear. As the Holy Spirit renews and refines us, we come to trust and love God, recognizing His immense love in sending His Son to die for us. Hell is real, fear is useful—but love is the destination and faith is the vehicle; may we let fear point us to Christ, and may we let love keep us there.
