Maybe, but actually eternal, like mortal are the natures of living matter, or life forms which are defined by principle.
For example, mortal is the nature of living matter, or a life form which has a) a beginning of life, or birth; and b) has an end of life, or death. In such, eternal is the nature of living matter, or a life form which has a) always existed; and b) will always exist.
The word nature denotes a beginning. God has no nature. He is not a man as us..
Supernatural is the beginning of eternal things not seen. This creation which was corrupted because of the fall as that seen is the temporal.. As new creatures we are given the faith of Christ which comes from hearing God not seen in order to see ahead to the new heavens and earth . The new generation, or genesis, the generation of Christ. The generation of Adam is limited to what the eye sees.
2Co 4:18 While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal.
Not the most popular but from my experience years ago someone gave their opinion on the other generation (beginning) not seen.
The word genesis was coined from the word generation. It could I believe read Generation 2:1-4, rather than Genesis 2:1-4
Note....(purple in parenthesis) by comments
Genesis 2:1-4 Thus the heavens and the earth were finished, and all the host of them. And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made.And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made. These are the generations (geneses plural) of the heavens and of the earth when they (plural)were created, in the day (singular)that the LORD God made the earth and the heavens,
It works the best for me when looking at the end and the new beginning below.
Revelation 21:23 And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof.
I will also add the following from Jesus::
Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me. John 5:39
They did not apply the prescription of Christ’s faith that comes from hearing needed to looking ahead to the eternal ( 2 Corintians4:18) They were looking at the things seen the temporal (their own flesh)rather than walking by faith the unseen eternal word.
They required a sign seen before they would believe making the cross without effect the stumbling block. Same block as today..
For the Jews require a sign, and the Greeks seek after wisdom:But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness; 1Co 1:22
