Isaiah 6:6-8 KJB
When Isaiah appeared before God in Heaven, and he saw the purity and holiness of God, he became keenly aware that he was a nasty sinner who had offended his righteous God. So, God sent an angel with a burning coal from off the altar to touch Isaiah's mouth and purge him of all his sins. These verses provide an example of how God holds the power to purge and forgive sins by His use of His fiery wrath against evil. Leviticus 5:10 (KJB).
God's power to forgive and cleanse sins and evil has to be directly connected to the sacrifice of His Son, the Lord Jesus Christ, because Jesus took the spiritual deaths, the sins, and the evil of the entire human race on Himself on the cross. I John 2:2 (KJB). Christ purges and forgives the spiritual deaths, sins, and evil of all His living humans whom He saves by His grace by washing them clean with His blood which He shed on the cross. Matthew 26:28; John 5:24; Revelation 1:5 (KJB). But that salvation does not become activated until a sinner repents and puts their faith in the power of Christ to save them. When they repent, the Holy Spirit baptizes them into the body of Christ. I Corinthians 6:11 (KJB). John the Baptist prophesied that Jesus would baptize with the Holy Ghost and with His fire. Luke 3:16-17 (KJB).
God sacrificed an animal for Adam and Eve to symbolize His shed blood for the salvation of all humans who would become saved by His grace. Genesis 3:20-21 (KJB). But after the great flood, God gave a burnt offering sacrifice of animals to Noah to symbolize His power to use His fiery wrath against evil to save the rest of humanity from sins and evil, but with a lesser form of salvation than that of grace. Genesis 8:20-21 (KJB). That lesser form of salvation has to be directly connected to the sacrifice of Christ for all of humanity. When Jesus died on the cross, He dismissed His Spirit who descended into Hell. Luke 23:46 (KJB). The Holy Spirit had to have had a reason to descend into Hell. The Holy Spirit descended into Hell to accomplish the burnt offering sacrifice for the lesser form of salvation of the rest of humanity. The Holy Spirit had to have borne all of the spiritual deaths, sins, and evil of the rest of humanity into Hell and left them there because He ascended completely uncorrupted from Hell to reanimate the perfect body of Jesus so that He could rise from the dead with a complete and absolute victory over all spiritual death, sins, evil, and the Devil. Psalm 16:9-11; Acts 2:25-31; John 12:31; Revelation 1:17-18; II Timothy 1:10; I John 3:8; I Peter 3:18 (KJB). But just like salvation by grace, this form of salvation cannot be activated until Christ causes the rest of humanity to repent and return to the faith that He put into them when He created them that He is their Savior. Revelation 5:11-14; Philippians 2:9-11; John 5:28-29; John 11:25-26; Habakkuk 2:4; John 12:32; II Peter 3:9-13; Romans 12:3; Revelation 21:1-5 (KJB).
Christ will use His fiery wrath against evil to purge all of His living humans who did not become saved by His grace of all of their sins and evil in the end of the world. Matthew 13:36-43; Luke 3:16-17; I Corinthians 3:11-15; Psalm 75:3; II Peter 3:9-13; Revelation 5:11-14 (KJB). "And all flesh shall see the salvation of God" because God the Father, the Son, and the Holy Spirit will save His entire, living human race that He creates in His image and whom He loves. Luke 3:6; I Timothy 4:10; Revelation 21:5; Luke 20:38 (KJB).
