2 Peter 3:13 “But, according to his promise, we look for new heavens and a new earth, in which righteousness dwells.”
We do not live on the new or renewed earth where righteousness dwells. The wicked still inhabit the earth.
Isaiah 66:22-23 “For as the new heavens and the new earth, which I will make, shall remain before me,” says Yahweh, “so your offspring and your name shall remain. It shall happen that from one new month (chodesh) to another, and from one Sabbath to another, all flesh will come to worship before me,” says Yahweh.”
I don’t claim to know the future, but it does appear that we will observe the Sabbath in the next age.
Hebrews 4:9 “There remains therefore a Sabbath rest for the people of God.”
