This booklet answers that very question. Assurance is not only essential for the serenity of the soul, it is also foundational to growing in the faith. We all struggle with fears and doubts, yet the Bible affirms a peace and joy for all who truly believe. This peace and joy flows from a genuine assurance of salvation. The precepts that establish complete and enduring assurance include understanding God's complete work of redemption, knowing you possess a genuine faith, resting in the security of salvation, and living out the practical process of assurance.
