In which book does Paul address the issue of sin and grace in relation to being slaves to righteousness?

The book of Romans is well-known for its theological depth regarding sin, grace, and the transformational journey of believers. In Romans, particularly in chapters 6 and 7, Paul addresses the concept of being "slaves" to sin versus being "slaves" to righteousness. He articulates how, through grace, believers are no longer bound by sin but are enabled to live righteously.

Paul introduces the idea of being united with Christ in His death and resurrection, emphasizing that through this union, individuals are freed from the dominion of sin. He contrasts the life under the Law, which resulted in sinfulness, with life in the Spirit, which leads to righteousness and holiness. The teaching highlights the transformation from being enslaved to sin to becoming servants of righteousness through the redemptive work of Christ.

Other books mentioned do cover aspects of sin and grace, but Romans specifically focuses on the profound theological implications of these concepts and how they affect the believer's identity and behavior, making it the primary text addressing the relationship between sin, grace, and righteousness in this manner.
