My wife and I have three dogs (a regular Chihuahua, a long-haired Chihuahua, and another which is a mix of a terrier and either a Rockweiler or Doberman – yes, go figure! How that happened is still mind-boggling to us). We now, also, have a cat who just appeared at our house and since my wife started feeding him, he’s ours! We love our dogs and, I suppose, our cat very much ;). They are adorable to us and make us laugh all the time and who else would get so excited to see us than they when we get home. Then they just follow us everywhere and want to be around us all the time. Many a times, they just make our day. When we see the news and see how some people mistreat and are cruel to animals, it just makes our heart cringe. However, God sure knew what He was doing when He made all of creation, including all the animals. So, when a student recently asked me if all dogs go to heaven, I was able to respond as best I knew how the Bible might answer this question.
The Bible does not mention it directly whether our pets (or, animals) will be in heaven, but it does give strong evidence that they will be. In the book of Genesis, when God creates the animals, He said that they were good (Gen. 1:25) and animals populated the garden of Eden. In the book of Revelation, the Apostle John’s vision of heaven also included animals, showing Christ and the armies of heaven “riding on white horses” (Revelation 19:14). In the book of Isaiah, Isaiah mentions that, “The wolf and the lamb will feed together, and the lion will eat straw like the ox, but dust will be the serpent’s food” (Isaiah 65: 25).
I believe these passages give us sufficient precedence for believing that animals will be in heaven and inhabit the new heaven and new earth.
