I for the longest time was at the opinion that our pets for example would not be in the kingdom because they could not receive the gift of Messiah or so I was taught.
When I started to look into Hebrew the term Nefesh came up ALOT, but also directed to animals. It made me think differently. Also animals are innocent as we know, so have no Iniquity and would not need to give of salvation? I am confident that in the kingdom YAHUAH has the ability and is the loving Elohim who would allow us to have our pets again just because he can. I also don't see any proof from scripture to show that it's a concrete no. I am optimistic that I will be with our dogs in the kingdom because of the love YAHUAH allows us to have for them and how much he loves us.
