How Can I Be Sure I’m Really Saved?

Share this:

Charles Haddon Spurgeon was a British Baptist preacher who began his London ministry as a nineteen-year-old in 1854 and remained in the same pastorate until his death at age fifty-seven. He was a phenomenon. Long before the modern megachurch, six thousand people crowded every service to hear him preach. No building seemed large enough to hold the masses who wanted to hear him. When he was only twenty-seven, Spurgeon preached to 23,654 people at the Crystal Palace—without amplification. Sometimes he would ask the members of his church not to attend on the following Sunday so that newcomers might find seats. Once in 1879, the entire congregation left so that newcomers waiting outside could enter, and still every seat was claimed.

Spurgeon’s messages were printed in newspapers and individually, with sales of single copies running up to 25,000 per week. His collected sermons fill sixty-three thick volumes, the largest set of books by a single author in the history of Christianity. Christian History magazine asserts that “Spurgeon is history’s most widely read preacher (apart from the biblical ones). Today, there is available more material written by Spurgeon than by any other Christian author, living or dead.” If evangelical pastors were surveyed as to their choice for the greatest preacher since biblical times, Charles Spurgeon would almost certainly be selected.

Occasional doubts are not only possible but also normal for Christians.

Surely a man of God with such a singular impact on millions for nearly two centuries would never doubt that he was a Christian. But in his autobiography, Spurgeon wrote of just such a battle: “I felt at that time very weary, and very sad, and very heavy at heart; and I began to doubt in my own mind whether I really enjoyed the things which I preached to others.” Despite his incredible influence, he wondered if he were an outsider to the Kingdom of God. “It seemed to be a dreadful thing for me to be only a waiter, and not a guest, at the gospel feast.”

If Spurgeon experienced doubts about his salvation, then less gifted, less influential Christians should not consider themselves strange for struggling with doubts. I’ve had them, and at times I still do. I’ve met very few Christians who claim they’ve never questioned the veracity of their faith. Spurgeon said, “I have known one or two saints of God who have rarely doubted their interest [in Christ] at all.” You are not abnormal if you have occasional doubts about whether you are a Christian.

The stated purpose of the letter of 1 John is to give assurance (see 5:13). Since this epistle was written to people the apostle John believed to be Christians and was written to assure them that they had eternal life, we learn that it’s possible to genuinely believe in Christ and not have assurance of salvation. True Christians can have at least occasional doubts about whether they are right with God.

Doubting assurance is not unbelief.

Doubt is not the same as unbelief. Imagine those rare Christians who say they have never had a single doubt about the reality and safety of their relationships with Christ. Now suppose some critics of Christianity confront them with what they (mistakenly) think are contradictions in the Bible and say, “If the Bible contradicts itself about this, how can you be sure it’s true when it speaks of Heaven, eternal life, etc.?”

These Christians may be completely unprepared for this kind of challenge. As they wonder what an informed response might be, they may even entertain the possibility that these critics are correct and consider the implications of such an outcome. The Christians’ bits of doubt are, however, qualitatively different from the critics’ unbelief.

Unbelief is unambiguous in its denial of certain things and clear about where it stands. Doubt is by definition unsure of its position. But doubt may lean in one of two directions. It may be skeptical doubt leaning away from faith and toward unbelief, or it may be doubt straining toward faith but lacking something. Often what is lacking is a more thorough understanding of the Bible. As pieces of the truth fall into place, they are wholeheartedly embraced.

You may be reading this book because you are leaning toward truth and want to believe. In fact, you may be reading it because you earnestly long for the assurance that you do believe savingly in Christ. If that describes you, I pray that you will find in these pages a clearer understanding of the truth of salvation and assurance.

The Causes of Doubt Are Many

Although it is normal for a true Christian to have occasional doubts, not every believer doubts salvation for the same reasons. Sometimes the doubt comes because of unrepentant sin. Sin grieves the Holy Spirit, and since He is the One who gives us the experience of assurance, when we grieve Him, we may temporarily lose our assurance. Sometimes spiritual indolence is the cause. Sometimes Satan accuses us and plants doubts in our minds. Sometimes the pressure of trials or harsh circumstances drives us to doubt our relationship with the Lord. Sometimes we doubt merely because of our physical or mental conditions at the time. Sometimes, even though we may not have caused it by sin, God withdraws a conscious sense of His presence from us (and with it a sense of assurance) so that we might learn to walk by faith and not by feelings or sight.

Spiritual immaturity may contribute to doubts about assurance.

Based on my own pastoral observations, the more recently it is that people have come to Christ, the more likely they are to have doubts about their salvation. They know less of the Word and ways of God than the mature. As your grasp of Scripture strengthens, so will the strength of your assurance. As you understand more of what God did for you in Christ, you will understand more of your true position before God in Christ. Also, the more you see God do in and through you, the more confident you will become of His saving grace in you.

Sensitivity to sin may cause confusion about assurance.

New believers especially doubt their salvation because they often misunderstand their new sensitivities to sin. The Bible says that “the god of this world has blinded the minds of the unbelievers” (2 Corinthians 4:4). When God saves people and removes their blindness, they not only see the things of God as never before, but they are given new vision into both righteousness and sin. They see their sin more clearly and are starkly aware of previously unperceived sins. They would have admitted to seeing a few sins in their lives before salvation, but with their new eyes they seem to discover sin everywhere.

If new Christians don’t understand why this is happening, they may think they’re not Christians at all. At first they felt clean, new, and forgiven, but now they feel sin-saturated.

Do you feel this way? If so, don’t panic. You should be encouraged to know that this new sensitivity to sin is actually one of the best signs that you are a Christian. It is extremely unlikely that you would have such concern unless the Holy Spirit was working within you. Why weren’t you so concerned about your sin before you repented and came to Christ? It’s because you were not indwelled by the One who makes you concerned about it (cf. 1 Corinthians 2:14). The Holy Spirit’s presence in a person makes that person sensitive to what is not holy within. Until He enters us, we are blind to all but our most obvious sins.

Comparison with other Christians may cloud assurance

New Christians also make themselves susceptible to doubts about their assurance when they compare themselves to more mature Christians. An apple tree in our backyard began to bear fruit during our first year in our home. But it didn’t bear nearly as much fruit that year as it did in the years that followed. New Christians should realize that just as a young tree isn’t as fruitful as a more mature one, so, too, new Christians shouldn’t expect to see as much evidence of the new life within them as they see in believers with longer and deeper roots.

When you are grieving over what you have not yet become, it often helps to remember how far you have come. What were you like before you professed faith in Christ? If there is biblical evidence that since then Christ has changed your life, don’t lose your assurance over the appearance of more or deeper changes in the lives of others.

Childhood conversion affects the assurance of some.

Besides new believers, there’s another category of Christians that seems particularly vulnerable to doubts. I have found that the younger in life a person was converted, the more likely that person is later to doubt the veracity of that conversion.

One reason for this tendency is that people who have been Christians since childhood—as I have—have few memories of life as non-Christians. You may not have seen the dramatic changes that sometimes accompany the lives of adult converts. When your Christian experience is basically the only life you’ve ever known, sometimes you wonder if the only thing you have known is the real thing.

Again, occasional anxiety like this is normal. It is spiritually healthy to have such concerns, for it reveals a concern the unconverted do not have—an eagerness “to confirm your calling and election” (2 Peter 1:10). The hearts of the unconverted are calloused, not sensitive to these things. They usually have a false sense of security and see no need for looking so intently into the states of their souls. But Christians may think, Could I be self-deceived? Lord, please don’t let it be so! If I’ve made a mistake somehow in thinking I’m saved, I want to know. If I’ve never repented and believed before, I want to now. Do these kinds of uncertainties and longings occasionally mingle in your heart? If so, you have reason to hope and to be encouraged.

  1. Spurgeon’s “doubt” was due to his Calvanistic theology…..its impossible for such to be sure of salvation. Selah!
