Charles Spurgeon's sermon "The Spirit of Bondage and Adoption" delves into the transformative journey from living under the oppressive fear of the law to experiencing the liberating grace of God's adoption. Spurgeon articulates the "spirit of bondage" as a phase where individuals are acutely aware of their sinfulness and their inability to attain righteousness on their own, leading to a servile fear. This fear, however, is instrumental in driving them towards Christ. Upon embracing Christ's redemptive grace, they transition to the "spirit of adoption," which brings freedom and a loving, respectful relationship with God, akin to that of a child to a parent.
