Leon Morris:
A good deal depends upon our conception of the place and nature of the wrath of God. If this is regarded as a very real factor so that the sinner is exposed to its severity, then the removal of the wrath will be an important part of our understanding of salvation; whereas if we diminish the part played by the divine wrath we shall not find it necessary to think seriously of propitiation.”
In other words, the good news cannot be fully appreciated unless we understand the bad news!
