He Won for Us Forgiveness, Adoption, and Glory

Packer:

The notion which the phrase "penal substitution" expresses is that Jesus Christ our Lord, moved by a love that was determined to do everything necessary to save us, endured and exhausted the destructive divine judgement for which we were otherwise inescapably destined, and so won us forgiveness, adoption, and glory.
