What Should I Do if I Have Doubts?
The question of rebaptism often leads naturally to concerns about salvation. Many believers who consider being rebaptized are not really asking about baptism—they are asking about their souls. They wonder whether they were truly saved the first time, whether their faith was genuine, or whether their sins have somehow separated them from God. These questions become even more pressing if they were raised in traditions that teach salvation can be lost.
In our last Bible Foundations class, we examined the work of Christ, and the conclusion was clear: the salvation accomplished through the sinless life, atoning death, burial, resurrection, and ascension of Jesus Christ is complete and sufficient. Scripture teaches that salvation is not achieved by human effort (Eph. 2:8–9; Titus 3:5), but by the finished work of the divine Son of God (John 19:30; Heb. 1:3). The Holy Spirit applies all the saving benefits of Christ to those who trust in him (Titus 3:5–6; Eph. 1:13–14). Because salvation is the work of God’s power (John 6:37, 44; Eph. 1:19–20), believers can be assured they have truly been born again.
The salvation accomplished through the sinless life, atoning death, burial, resurrection, and ascension of Jesus Christ is complete and sufficient.
For that reason, it is impossible for a true Christian to lose their salvation. Eternal life is eternal because God keeps his people. Jesus confirms the Father’s will:
“…that I should lose nothing of all that he has given me…” (John 6:38–40).
He reinforces this promise when he says:
“My sheep hear my voice… they shall never perish…” (John 10:27–29).
Paul adds:
“There is therefore now no condemnation for those who are in Christ Jesus.” (Rom. 8:1)
The Spirit himself seals and guarantees our inheritance (Eph. 1:13–14). And the God who began a good work in us “will bring it to completion at the day of Jesus Christ” (Phil. 1:6).
These verses—and many others—form the biblical foundation for what Christians have historically called the perseverance of the saints. True believers persevere not because their grip on Christ is strong, but because Christ’s grip on them is unbreakable.
What Should I Do if I Have Doubts?
Christians do not lose salvation, but they can lose a sense of assurance. Scripture never rebukes believers for struggling with doubt; instead, it directs them toward the truth that restores confidence. Doubt can arise from many places—past sin that still burdens the conscience (Ps. 51:12), emotional discouragement (Ps. 42:5), spiritual immaturity (Eph. 4:14), or even years of exposure to teaching that threatens believers with the possibility of falling away (Gal. 1:6–7). Understanding where the doubt comes from is helpful, but the remedy is always the same: we return to Christ.
Christians do not lose salvation, but they can lose a sense of assurance.
Assurance does not come from analyzing the quality of our performance; it comes from resting in the promises of God. Scripture directs our attention away from ourselves and toward the unchanging character of Christ, the reliability of the gospel, and the testimony of the Spirit in our hearts (Rom. 8:15–16). A trembling faith is still true faith, because the strength of salvation lies not in the one who believes but in the One who saves.
When doubts arise, the Christian should ask a simple but clarifying question: “Do I trust Christ today?” The Bible never invites us to examine whether our conversion experience was dramatic or emotional enough. Instead, it points us to present faith (1 John 5:13). Saving faith is not measured by intensity but by dependence—do I rely on Christ, however weakly? If the answer is yes, Scripture assures us that we belong to him.
Christ has also provided the ordinary means of grace to strengthen assurance—his Word (Rom. 10:17), prayer (Phil. 4:6–7), worship (Ps. 73:16–17), fellowship with other believers (Heb. 10:24–25), and obedience to his commands (John 14:21). These are not mechanical rituals but relational pathways that draw the believer closer to Christ. They nurture the believer’s confidence by deepening communion with God.
Saving faith is not measured by intensity but by dependence.
Pastoral counsel is also a gift. God has placed shepherds in the church to care for souls (Heb. 13:17). A wise pastor can often see clearly what a troubled conscience cannot.
A doubting Christian is not a lost Christian. Doubt is a call to anchor the heart again in the objective promises of God.
Obedience, Assurance, and the Work of God
It is important to clarify the relationship between obedience and assurance. Scripture is clear that salvation is not earned by obedience (Eph. 2:8–9). At the same time, Scripture is equally clear that no one is saved without obedience (Heb. 12:14; John 14:15; 1 John 2:3–4). The distinction is vital: obedience is not the cause of salvation; it is the evidence of salvation. It is the fruit that grows from a heart already made alive by the Spirit (Eph. 2:10; Gal. 5:22–23).
Because obedience is a mark of genuine faith, it naturally strengthens assurance (1 John 2:3). But we must never ground our confidence in our religious performance. Good works point us to the reality that God is at work in us, but they do not form the foundation of our acceptance before him. That foundation is Christ alone—his righteousness, his blood, his intercession, his promise.
Obedience is not the cause of salvation; it is the evidence of salvation.
A Christian cannot be saved without obedience, because saving faith always produces obedience. But a Christian is never saved by obedience (works), because only Christ’s righteousness saves. Obedience is the fruit of salvation, not its root. It is empowered by the Holy Spirit, not generated by human strength (Rom. 8:13; Phil. 2:12–13).
Therefore, the believer’s assurance rests ultimately not on personal performance but on the character of God—on the Father who calls, the Son who saves, and the Spirit who seals. The God who began the work will finish it. Our obedience is the evidence that he is doing exactly that.
Closing Encouragement
If you struggle with doubt, take heart: the presence of doubt does not mean the absence of salvation. The very fact that you care about your soul is itself evidence of the Spirit’s work within you. Look again to Christ. Root yourself in his promises. Walk in fellowship with his people. And remember that the same God who saved you is the One who keeps you.
