John Shower has one main doctrine to expound in this important work: Pardoning mercy is the most valuable mercy. There is no blessedness in this world like knowing we are forgiven. And yet God does not merely pardon; according to the prophet Isaiah, “He will abundantly pardon”(Isa. 55:7). It is in this area that we most see how different God’s ways and thoughts are from ours. While man struggles to forgive, God abundantly pardons! But first the sinner must forsake his ways and thoughts, return to the Lord, and then embrace God’s ways and thoughts, which are higher than the heavens are above the earth—and so is His forgiveness.
