There are problems with Penal Substitution. I address five problems in this video.
1- No scriptural support. 2- No logical place for forgiveness 3- No logical place for mercy from God the Father 4- Penal Substitution logically ends in Limited Atonement or Universalism. 5 - Sin can't be transferred.
