WEEK 2
The Assurance of Salvation
Central Truth:
God intends for every believer to know with confidence that they possess eternal life, based on the promises of His Word rather than on feelings.
“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.” — 1 John 5:13 (NKJV)
Background:
Many sincere believers struggle with doubt about their salvation because they base their assurance on feelings, on how consistent their prayer life has been, or on comparing themselves with other believers.
Scripture does not leave this matter to guesswork. God has given clear, objective grounds on which a believer can rest a settled assurance of salvation. This lesson builds on the new birth by establishing that assurance is a normal and healthy part of Christian living.
Teaching Outline:
1. Assurance Is Based on the Testimony of God's Word (1 John 5:11-13)
John states plainly that God has given believers eternal life, and this life is in His Son. He wrote his letter specifically so that believers could know, not merely hope, that they possess eternal life. Assurance is not presumption; it is simply believing what God has already declared in Scripture concerning everyone who has trusted Christ.
2. Assurance Is Confirmed by the Witness of the Spirit (Romans 8:15-16)
The Holy Spirit Himself bears witness with the believer's spirit that they are a child of God. This inward confirmation does not replace the objective testimony of Scripture; it works alongside it. A believer who has been adopted into God's family no longer relates to God with the fear of a slave, but with the confidence of a child calling out to a loving Father.
3. Assurance Is Evidenced by a Changed Life (1 John 3:14; 1 John 2:3-5)
John gives practical tests of assurance, including love for other believers and a growing obedience to God's commands. These are not the basis of salvation, since salvation is by grace through faith, but they are evidence that genuine faith is present.
A life with no growth, no love, and no desire for obedience should prompt honest self-examination rather than false comfort.
Illustration:
A man who has signed a legal deed to a piece of land does not need to feel like the owner of that land for the deed to be valid. The deed itself is the proof of ownership, regardless of his emotional state on any given day. In the same way, the believer's assurance rests on God's unchanging Word, not on the shifting emotions of a particular day.
Life Application:
Stop measuring your salvation by your feelings on any given day, and anchor your assurance in the promises of God's Word.
Ask the Holy Spirit to deepen your confidence as His child through prayer and time in Scripture.
Examine your life honestly for growing evidence of love for God's people and a desire to obey Him.
Discussion Questions:
1. Why do many believers struggle with doubt about their salvation even after being genuinely born again?
2. What is the difference between the objective ground of assurance and the felt experience of assurance?
3. How does the witness of the Spirit work together with the written Word to confirm assurance?
4. What evidences of salvation can you point to in your own life over the past year?
Prayer Focus:
Pray for believers battling doubt to receive a settled confidence in God's promises. Pray for the Holy Spirit to bear fresh witness to every heart in the class. Thank God for the certainty of eternal life given through His Son.
Assignment for the Week:
Read 1 John 5:1-13 and Romans 8:14-17.
Write out in your own words why you can be sure you have eternal life.
