That's not getting anyone into heaven. "Nothing but the blood of Jesus..."
But what does it say? "The word is near you; it is in your mouth and in your heart," that is, the word of faith we are proclaiming: That if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved. As the Scripture says, "Anyone who trusts in him will never be put to shame."
Romans 8:8-12
I need to check that poem. It was a good one though. Besides its good to be nice to dogs. And cats.
