Do You Know For Sure?
Discovering the assurance of salvation through faith in Christ
1 John 5:13 — “I write these things to you who believe in the name of the Son of God that you may know that you have eternal life.”
Opening Reflection
Everyone wonders at some point: What happens when I die? The Bible offers a confident answer. John’s words were written so that believers could know they have eternal life (1 John 5:13). God’s desire is not uncertainty, but assurance—built not on emotion or performance, but on His unchanging Word.
Taking a Devotional View
Salvation begins with recognizing need. “All have sinned and fall short of the glory of God” (Romans 3:23). Sin separates us from God, but His love bridges that gap: “God shows His love for us in that while we were still sinners, Christ died for us” (Romans 5:8).
Salvation is received through faith, not works. “If you confess with your mouth that Jesus is Lord and believe in your heart that God raised Him from the dead, you will be saved” (Romans 10:9–10). Salvation is “the gift of God, not a result of works” (Ephesians 2:8–9).
Assurance comes from God’s promise, not our performance. Faith rests in what God has done, not in what we do. When we trust Jesus Christ alone for salvation, His Word declares that eternal life is already ours. The Spirit Himself confirms this truth in our hearts, replacing fear with peace.
