“Will my pet go to heaven?”
As a pet owner and lover, I have no small vested interest in the question myself. That said, given what I know of God, if it turns out that my much-loved critters do not appear beside me in glory one day, I will not be turning to my heavenly Father to complain. There is simply too much about my own consciousness that I do not know with certainty for me to speculate with any confidence about animal consciousness and its eternal value.
Some things we simply have to leave to God. If there is a distinction to be made between the concepts of faith and trust, I would not be able to tell you what it is. Among Christians, then, who have already committed our own selves to Christ for salvation, a little trust on these smaller matters is in order.
