For as the new heavens and the new earth, which I will make, shall remain before Me, saith the Lord, so shall your seed and your name remain. (Isaiah 66:22)
The present heavens — and Earth (which is our home, for now) — are finite and temporal; they shall ultimately be replaced by new heavens and new Earth. (See also Mark 13:31; 2nd Peter 3:7-13; Revelation 21:1.) All the more reason to live for the Lord Jesus in the here-and-now, so that each day counts toward the hereafter.
So, even while living here (and now) below, we keep in mind our real homeland (Philippians 3:20). For a creationist-ecologist’s perspective on appreciating “home”, see my article “Why We Want to Go Home”, ACTS & FACTS, 44(4):20 (April 2015), posted at http://www.icr.org/article/why-we-want-go-home .
