Those who reject Jesus Christ and continue in rebellion against God will go to hell. The Bible clearly states that those who do not believe in Jesus stand condemned and face eternal separation from God (John 3:18). Hell was prepared as a place of punishment for Satan and his demons, but it is also where individuals who refuse to surrender and follow Jesus will end up (Matthew 25:41–46). The Bible emphasizes that eternal life with God is available through faith in Jesus, but those who choose to reject this offer remain in sin and will face its consequences in hell (Romans 6:23).
In modern times, the idea of hell has come under doubt, even among some popular Christian authors, teachers, and pastors. We so badly want to believe that no one will have to suffer an eternal separation from God that we begin to develop our own ideas of what is true and fair and just. However, this thinking simply puts us in the place of God. It is He who determines what is true, fair, and just. And, in His Word, the Bible, He has made it clear that hell exists and those who continue in their rebellion against Him, who do not accept His way of getting out of rebellion through His Son Jesus Christ, will go to hell.
But hell can also be avoided. We avoid hell by recognizing our sin, agreeing with God that we are guilty before Him, and then believing in Jesus. We acknowledge that Jesus is God, that He paid the price for our sin by dying on the cross, and that He has risen victorious over death and sin (Romans 10:9). We ask for His forgiveness and then seek to follow Him. Jesus took on and paid for our sin so that we might take on His righteousness (2 Corinthians 5:21). It is by His grace, through faith, that we are saved (Ephesians 2:8–9). We cannot earn our way out of hell. Instead, we receive God's free gift through Jesus (John 3:16–18). For those who put their faith in Jesus, eternity will be spent in heaven, where God dwells (2 Chronicles 30:27) and where Jesus is preparing a place for those who love Him (John 14:2).
It is up to each of us where we will spend eternity. God wants each person to choose His way and spend eternity with Him (Matthew 18:14; 2 Peter 3:9), but He will not force us to choose Him (John 4:14). As John wrote, "He was in the world, and the world was made through him, yet the world did not know him. He came to his own, and his own people did not receive him. But to all who did receive him, who believed in his name, he gave the right to become children of God" (John 1:10–12).
C. S. Lewis said it this way: "There are only two kinds of people in the end: those who say to God, 'Thy will be done,' and those to whom God says in the end, 'Thy will be done.'"
