Biblical Assurance
Part 1
August 6, 2025

The study examines assurance of salvation (drawing on Westminster Confession 18 and Shorter Catechism 36), arguing that true assurance is an infallible confidence in our status as God's children grounded in justification and adoption (not sanctification), is possible though not guaranteed in this life, can be undermined by false hopes, hypocrisy, forgetfulness and Satanic attack, and is evidenced by sincere faith, love, obedience, a clear conscience, and repentance—all rooted in Christ's finished work and the Spirit's application.
Summary
This study explores the doctrine of assurance, using Westminster Confession chapter 18 and Shorter Catechism 36 to define assurance as the believer's confident status as a son or daughter of God grounded in justification and adoption rather than in sanctification. It warns against false hopes—self-deception, hypocritical confidence, and fleshly presumptions—and notes that assurance can ebb and flow even though it is possible in this life because of Christ's finished work applied by the Spirit. Key conditions for assurance include true faith in Christ, sincere love (distinct from perfection), striving to walk in good conscience, ongoing repentance, and obedient living; the study also highlights obstacles such as Satan's accusations, comparison with others, imperfect memory or understanding, and the pastoral need to examine our hopes and learn from wrong decisions.
Key Points
- Topic and sources: study on assurance using Westminster Confession (ch. 18) and Shorter Catechism (Q.36).
- Definition: assurance = infallible confidence in our status as God's children, rooted in justification and adoption rather than in sanctification.
- Possibility vs guarantee: assurance is possible in this life because of Christ's finished work, but it is not always guaranteed and may ebb and flow.
- False hopes and dangers: hypocrisy, self-deception, fleshly presumptions, forgetfulness, and Satanic accusations can produce false assurance or undermine true assurance.
- Basic conditions for genuine assurance: true belief in Jesus, sincere love (not perfection), striving to walk with a clear conscience, ongoing repentance, and trust as part of faith.
- Obedience and assurance: genuine obedience and faithfulness to Scripture are closely connected to experiencing assurance; sincerity (doing your best with given grace) matters.
- Practical counsel: examine your hopes and presumptions, learn from wrong decisions, avoid unhealthy comparisons, use community resources (e.g., memory partners), and remember the finished work of Christ as the foundation of assurance.
- Pastoral nuance: recognize pastoral concerns (some fear assurance as dangerous) and balance the objective foundation in Christ with subjective struggles believers face.
