Proverbs 6:27-29 KJB
One would think that if a person took fire into his bosom, then his belly and his clothes would be burned. And if a person walked on fiery coals, then his feet would be burned. But there are people who walk on fiery coals, and their feet do not get burned. But they report that they have strange feelings after they do that. These verses liken sin to fire which a person may play with for a while and not get burned, but their conscience and their innocence will always be burned.
The person who commits adultery may seem to get away with that sin, but his innocence is damaged. Many people play around with sin for a long time, and they enjoy its pleasures for a season, but in time their sins will start to severely burn them. Sin will eventually take their health, their money, and they may even wind up in prison. But even if they seem to get away with sin, it always hardens their conscience.
God understands that humans are too weak to avoid sin. All humans inevitably sin. Romans 3:23 (KJB). For this reason, God often does not directly punish a person for their sins, but He will allow the destructive effects of continued sin to break a person so that they may turn to Him when they hear the gospel and repent and put their faith in Christ who alone can save them from their sins. Romans 5:5-9 (KJB). God will also sometimes save young people who were raised in Christian homes because He makes them understand how destructive sin will be in their lives and that God will send them to one of the three regions of death if they do not repent. II Timothy 3:14-15 (KJB). All humans saved by grace try very hard to avoid sin because they love the Lord, and they hate sin. Yet even humans saved by grace sometimes sin, but God will always forgive them when they confess and repent. I John 1:5-10 (KJB).
Sin happens to be inevitable, but the practice of evil is not inevitable. A person becomes evil because their conscience becomes so hardened that they become capable of committing terrible acts of cruelty to their fellow humans. Evil humans decide to become evil. Extremely evil humans seldom become saved by grace because they hate God. The Bible records that the only evil person who became saved by grace was Saul of Tarsus. Acts 9:1-6 (KJB).
Those who hate God will also hate His believers. John 17:14 (KJB). Yet Jesus commanded His believers to "Love your enemies." Luke 6:27 (KJB). His commandment can only mean God loves His enemies. But God also hates evil. Psalm 45:6-7 (KJB). Like God, Christians should hate sins and evil, but, like God, Christians can love their enemies because God creates every human in His image with the capability of repentance, love for God, and reconciliation with God. Genesis 1:31; Genesis 1:26-27; II Peter 3:9 (KJB). The Holy Spirit has written that God will "reconcile all things to Himself." Colossians 1:20 (KJB). Christ has promised: "Behold, I make all things new." Revelation 21:5 (KJB). This Word of God can only mean that God has a plan to cause all of His living humans eventually to repent and return to faith in Christ as their Savior. John 5:24; Revelation 5:11-14 (KJB).
God never uses His fiery wrath to permanently burn anything except sins, evil, spiritual death, and the Devil. Revelation 20:11-15; Revelation 20:10 (KJB). God uses His fiery wrath against evil to permanently purge His creation of all sins, evil, spiritual death, and the Devil so that He can recreate it all to be wholly righteous, including all of His living humans who have been soiled by sin and evil. II Peter 3:9-13 (KJB).
