The concept of newness in Scripture is deeply tied to the Greek word *kainos* (G2537), which emphasizes a radical change in nature or quality, distinct from *neos*, which focuses on newness in time or origin. *Kainos* represents something unaccustomed or unused, not merely recent, but transformed in its essence compared to its former state. This is evident in Peter's use of *kainos* to describe the emergence of a gloriously renewed universe, highlighting a freshness and quality that is unstale and fundamentally different. In the context of spiritual transformation, *kainos* is associated with profound changes brought by God's work in believers. It signifies a new covenant, a new commandment, a new creative act, a new creation, and a new man, reflecting a spiritual and moral character patterned after Christ. Paul calls for those in Christ to put off old natures, be renewed in the spirit of their minds, and put on this new nature, as seen in Ephesians 4. This new man, described with *kainos* in Ephesians 2:15, differs in character, marking a significant shift from the old self. Moreover, in the book of Revelation, elements related to the Kingdom of God are marked by *kainos*, indicating a freshness and excellent quality. These include a new name, a new song, a new heaven and earth, the New Jerusalem, and God's proclamation to make all things new. This newness is not merely a replacement of the old but a transformation that perfects and completes it, embodying the eternal nature of God where righteousness flourishes as a permanent aspect.

The time is coming when no unrighteousness in any form, including angelic sins, exists in God's New Heaven and New Earth. Isaiah 65:17 provides a clear view of this breathtaking circumstance, declaring that God will create new heavens and a new earth, where the former things shall not be remembered or come to mind. A world is approaching in which not even the memory of sins or sinners exists, as God purges sin and unrepentant sinners from existence. Revelation 20:11-15 and 21:1 confirm that all sinful works done on earth, including those of sinning angels, will be burned up in the Lake of Fire. The prophecies describing the level of righteousness in the New Heaven and New Earth allow no room for any sin at all, ensuring a pure moral and spiritual environment where nothing will mar the loving relationships in God's Family Kingdom.

In the discussion of the new creation, the term "kainos" (G2537) is deliberately chosen over "neos" to convey a specific meaning. "Kainos" indicates newness in the sense of a fresh existence, a complete transformation rather than a mere renovation of something already existing. This term is used to describe the transformation in the inner man from carnal, self-centered thinking to spiritual thinking and conduct. It signifies a new creation, not just a repair of the old carnal nature, but a nature that has not existed before conversion. This concept parallels the creation of Adam, who was a new creation when God breathed life into him. Similarly, in the Kingdom of God, individuals are made every bit as new, with a new heart and nature that produce righteousness in contrast to the old nature that produced sin. This newness extends beyond personal transformation to include a New Heaven and New Earth, which will be just as fresh and unprecedented. The use of a Hebrew term in Isaiah, equivalent to "kainos," reinforces this idea of something absolutely new, emphasizing God's purpose of creating a world where sin and sinners are purged from memory and existence.
