Scripture consistently presents salvation as something accomplished by Christ, not completed by us.
If assurance is impossible, one of two things is true:
either Christ’s work was insufficient,
or assurance was never meant to be withheld.
1 John 5:13 says, “These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life…”
What This Means:
God never intended for salvation to feel uncertain or fragile. Through the apostle John, He gives believers a clear and unshakable promise: eternal life is something we can know, not merely hope for.
This assurance isn’t based on emotion, performance, or spiritual highs — it’s grounded in the finished work of Christ and the reliability of God’s Word.
1 John 5:13 teaches that:
Assurance is part of the Christian life, not an optional bonus.
Belief in Christ is the foundation, not our fluctuating feelings.
God wants His people confident, not confused or insecure.
This verse stands as a reminder that the security of our salvation rests in God’s promise, not our perfection. When we believe in the name of the Son of God, Scripture says we may know — with certainty — that we have eternal life.
