Assurance of salvation is grounded in the testimony of Scripture, particularly 1 John 5:13, which states that believers can know they have eternal life.
The doctrine of assurance, teaching that believers can have certainty regarding their salvation, is firmly supported by Scripture. For instance, 1 John 5:13 explicitly declares, "These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life." This verse affirms that assurance is not only desirable but also attainable.
This assurance is rooted in the transformative work of the Holy Spirit, who not only regenerates believers but also provides them with evidence of their faith and relationship with God. Paul’s prayers often reflect the desire for Christians to grasp this assurance through enlightenment, as seen in Ephesians 1:18, where he prays for the understanding of their hope and inheritance. Thus, assurance is essential for a faithful Christian life, enabling believers to live confidently in the grace offered through Christ.
