Greater Sins, Greater Grace: Degrees of Sin and the Depths of Divine Forgiveness

by Jeff Moore

When Sin Is Serious―and Grace Is Greater

Greater Sins, Greater Grace by Jeff Moore confronts a question many Christians assume is Are all sins equal? With pastoral clarity and rigorous scholarship, Moore demonstrates from Scripture that while all sin brings guilt before God, the Bible itself distinguishes degrees of sin―and magnifies the depth of divine grace that meets even the gravest offenses.

Rooted in careful exegesis of both the Old and New Testaments, this book challenges popular evangelical slogans with a whole-Bible theology of sin, judgment, and forgiveness. Moore guides readers through difficult moral terrain with courage, precision, and compassion, showing why certain sins strike more directly at God’s created order―and why the gospel still offers hope to those who repent.

Written for pastors, students, and thoughtful Christians, Greater Sins, Greater Grace equips the church to speak truthfully, preach wisely, and extend grace boldly in a morally confused age.

[Logan S · Rating 4.5 out of 5]

Overall I thought this was a very engaging and thoughtful book on a topic that many Christians are confused about—the slogan “all sins are the same in God’s eyes persist today and is one I used to believe myself. My only quibble is that there were a couple of places where his exegesis seemed faulty to me. First was his argument over the unforgivable sin and it only applying post-Pentecost. I’d need to do more reading on that but it seems a head-scratching interpretation to me in the context of the passage. Second, on page 47 his argument that Romans 1:26 is concerning women exchanging natural sexual use with their male partners instead of addressing women being filled with just for other women—lesbianism—is almost surely wrong given that verse 27 says “likewise” and then speaks of men being filled with just for other men. I noticed he doesn’t footnote any commentator who might support his interpretation which adds to my skepticism that his interpretation is accurate. Though these interpretations caused me to scratch my head, they did not affect his overall thesis, which I found sound.
