Psalm 104:4 KJB
This Psalm is mostly about God's creative powers, and His recreation after He had destroyed most of the humans and the animals in the great flood, but He recreated it all. God used water to purge the earth of evil humans so that He could preserve a better human race in Noah and his family. The constant goal of God is to purge His creation of all sins, evil, and the Devil so that He can recreate it all to be wholly righteous. II Peter 3:9-13 (KJB). After the great flood, God made the human race better, but each individual human still retained a spiritual death inside of every one of them that the Devil injected into them whenever they sinned. Genesis 2:17; Genesis 3:15 (KJB). Noah's sin after the flood proved that to be the case.
The Psalmist rejoices over the joy and beauty of God's creation as if it had no sin and evil within it. The Psalmist concludes with a plea to God that He consume and purge all sinners and all evil from His creation. Psalm 104:35 (KJB). In the end of the world, God will use His fiery wrath against evil to purge and cleanse His creation of all sins, evil, spiritual death, and the Devil so that He can recreate it all to be wholly righteous. II Peter 3:9-13 (KJB). At that time, Christ will visit all of His living humans whom He created in His image who are "on the earth, and under the earth," and He will cause them all to repent and believe in Him as their Savior so that He can use His fiery wrath to dissolve their beings to separate their repentant, good and living natures from their dead and evil natures. Christ will then recreate their good and living natures with new bodies to live forever on His recreated earth, and He will cast their dead and evil natures into an eternal lake of fire. Revelation 5:11-14; Revelation 20:5; Revelation 21:1-5; II Peter 3:9-13 (KJB).
Since God is "not willing that any should perish, but that all should come to repentance," then the entire human race will eventually repent and be saved because God's Will cannot be thwarted. II Peter 3:9 (KJB). When God uses His fiery wrath to burn the heavens and the earth, He will burn all of the evil works of the Devil, including all of the evil within the inner beings of all humans who did not become saved by God's grace. II Peter 3:10 (KJB). All of God's creation will be dissolved to separate the evil from the good, including all of God's living humans whom He will cause to repent. II Peter 3:11; Psalm 75:3 (KJB). Even living humans saved by grace will be somewhat dissolved because God will wash away all of their sins and evil with the blood of Jesus, and He will annul their spiritual deaths, and He will recreate them from the inside out. I John 1:7; John 5:24; II Corinthians 5:17 (KJB). After God has thoroughly purged His entire creation of all sins, evil, spiritual death, and the Devil, He will recreate it all to be wholly righteous, including all humans whom He has created in His image. II Peter 3:13; Revelation 21:1-5 (KJB).
The Psalmist interrupts his paean to the glory of God's creation to relate that God can delegate His fiery power to His angels and His ministers. God can use His angels to punish evil humans, and God can also empower His ministers with His fiery power to preach His Word. Psalm 104:4; II Kings 19:35; Acts 2:1-4 (KJB).
