The reality of the Spirit of adoption is evidenced by the profound love and trust believers experience toward God (Romans 8:15).
The assurance of the Spirit of adoption is manifest in the transformative love and faith that characterize the believer's relationship with God. Romans 8:15 emphasizes that this Spirit imparts not just a title, but a nature that enables believers to relate to God not as servants, but as beloved children. This relationship fosters a love that is intimate, trusting, and reverential. As believers grow in this relationship, they experience a unique blend of love and awe, indicative of the work of the Holy Spirit in their lives. The Spirit inspires a filial obedience that reflects the believer's heart; they desire to keep God's commandments not out of fear, but from a deep-seated love engendered by the Spirit of adoption. Thus, the presence of such profound love and trust serves as evidence of the Spirit at work within the believer.
