God's Asymmetrical Mercy and Justice
The book emphasizes the asymmetry between God's mercy and justice, highlighting that while generational sins may affect up to the third or fourth generation, God's covenant love extends to a thousand generations. This disproportionate emphasis on mercy over justice is a central theme. 'His covenant love flows down to a thousand generations; but he visits generational sins to the third or fourth generation.' This idea is illustrated through the comparison of God's self-revelation in Exodus 34:6-7, where mercy and love are prominent, and retributive justice is mentioned almost as an afterthought.
