Hebrews 1:2 defines these last days: when Jesus the Son of God spoke us. He is the heir of all things and through whom the world was made. The last days began with Jesus’ birth and consummates with his return.
Kitisis can mean creation, a building, a creature or a law. Each of these has an example in scripture. For example, 1 Peter 2:13 speaks of every ordinance of man “anthropine ktisei”. An example of this expression meaning the first law is in Mark 10:6. The disciples asked Jesus whether it was lawful for a man to divorce his wife. Jesus said it was not so from the first law (arch ktisis). God commanded that a man should leave his father and mother and cling to his wife. No mothers and fathers existed at this stage, so this was the first law for all human societies. Please notice that the context is not the beginning of creation but laws. Moses modified God’s first law because of the hardness of their hearts. Besides this law was not pronounced at the beginning of creation, but on the sixth day. In 2 Peter 3, again the context is not about the beginning of creation but the first law of the last day mockers. What do they do with their law? They obfuscate cosmic and Earth history which is what modern scientists do Why? The structure of Western science was built on the medieval scholastic assumption that “the essence of substance is changeless”, that matter’s intrinsic properties are fixed.
This is why changing earth creationists expect that God will abase the pride of man in their science, for his great glory. Why would God do this? Man cannot come to faith through science. He saves us for his glory and no man will be able to boast in his presence.
