Assurance in Christ Alone

Saved by Grace… So, Why Don’t I Feel Saved?

Something every Christian wrestles with at some point is the question of assurance. Simply put, assurance is the confidence that Christ’s work — His birth, His life, His death, and His resurrection — is truly enough for our salvation.

And yet, in different seasons of life, this confidence wavers. Why?

Because many of us, depending on our background, slowly drift from trusting Christ to evaluating ourselves.

We start asking:

  • “Am I doing enough devotional time?”
  • “Am I serving my neighbor enough?”
  • “Why did I fall into that sin again?”
  • “Will God really forgive me when I’ve failed this many times?”

And suddenly, without realizing it, we’re drowning in the weight of our own performance. We forget the One who has already performed everything necessary for our salvation.

Don’t misunderstand me — good works matter. They are the fruit of faith. But they are not the foundation of assurance, nor do they do anything for our salvation.

When we look inward for certainty, we will always find:

  • inconsistency
  • weakness
  • sin
  • doubt
  • shifting emotions

This is why assurance must come from outside of us, not from within.

God has given us something objective: His Word, proclaimed and delivered through preaching, Scripture, and the sacraments. Through these, the Holy Spirit speaks forgiveness, justification, and peace — not based on what we have done, but on what Christ has done for us.

The moment we turn inward, our subjective feelings begin to cloud the truth. And this is where the real struggle begins: objective truth vs. subjective feelings — and why so many believers fall into despair about their salvation.

This is the tension we need to explore.

To get to the heart of this struggle, we have to return again to the Scriptures — not to our feelings, not to our performance, but to the objective truth God has spoken. The Bible is where our assurance is grounded, because it reveals that our salvation is secure in Christ alone. There are many passages that speak to this confidence, but there are two in particular that I want to draw your attention to. These passages remind every weary, doubting believer that the work for your salvation is complete, and that nothing you do, no sin you fall into, and no accusation from the enemy can take Christ’s finished work away from you.

First, 1 Corinthians 15, often called the Resurrection Chapter, is where we begin. Here Paul reminds the church in Corinth — a church with more issues than we can count — that their salvation is secure because Christ has been raised from the dead on their behalf.

Paul writes:

“Now I would remind you, brothers, of the gospel I preached to you, which you received, in which you stand, and by which you are being saved, if you hold fast to the word I preached to you—unless you believed in vain” (15:1–2 ESV).

Do not gloss over Paul’s phrase: “by which you are BEING SAVED.” This is an active verb. Not passive. Not past tense. It describes a continual action — Christ’s ongoing work for you. This is the gospel in its purest form, and hopefully what you hear each week, not some “do better, be better, get better” TED Talk from a stage.

The fact that Paul, this far into his letter to a wacky, broken bunch of sinners, reminds them of this truth is one of the greatest assurance passages in all of Scripture.

Another part of this chapter that strengthens our assurance — even apologetically — is how Paul roots the resurrection in real history, witnessed by real people, whom he openly invites his readers to go talk to. Paul is essentially saying, “Go verify this. Ask the eyewitnesses.” That is a bold move for anyone, let alone an ex‑Pharisee who staked everything on the resurrection.

Paul writes: “That he (Jesus Christ) appeared to Cephas, then to the twelve. 6 Then he appeared to more than five hundred brothers at one time, most of whom are still alive, though some have fallen asleep. 7 Then he appeared to James, then to all the apostles” (1 Cor 15:5–7 ESV).

Then Paul adds that Christ appeared to him as well — an event recorded in Acts 9.

Paul’s point is clear: the resurrection is not a myth, not a metaphor, not a spiritual idea. It is a historical fact, testified by hundreds of living witnesses. And Paul builds his entire life, ministry, and theology on this truth.

He goes on to say — and here I summarize verses 16–19 — that if Christ has not been raised, then our faith is empty and we are the most to be pitied. Why? Because if we believe that a Jewish man was crucified but not raised, then we are believing in nothing at all. Even the Romans and other ancient cultures believed in gods who could supposedly do something for you if you offered enough sacrifices. But Christians believe something unheard of: that Christ was crucified, buried, and raised from the dead for our justification before the Father who is in heaven. Paul lived and died by this truth.

Read the rest of the chapter to grasp the full weight of Paul’s argument. Yet before we move on, I want to highlight one more statement from Paul that offers deep comfort to anyone struggling with assurance.

Next is Galatians 3, a beautiful portion of Scripture where Paul once again confronts those who oppose his message that Christ is enough for the salvation of all creation. The Galatian church, much like Corinth, had its own major issues. You can hear Paul’s tone — even his frustration — as he addresses a congregation being deceived by the “circumcision party,” likely a group of Pharisees or others who were fine with Christ as long as you added something to His finished work.

Paul will have none of it. For him, it is Christ alone or nothing at all. You cannot add to the finished work of Christ — God in the flesh — for the salvation of sinners.

Yet in the middle of this strong correction, Paul makes a pastoral move. He reminds this struggling church — sinners though they are, as we all are — that they are still saved by Christ alone. And he grounds this assurance in something deeply personal and concrete: their baptism.

Paul writes:

“But now that faith has come, we are no longer under a guardian, for in Christ Jesus you are all sons of God, through faith. For as many of you as were baptized into Christ have put on Christ” (Gal 3:25–27 ESV).

This is the summation of Paul’s argument up to this point.

The “guardian” Paul mentions refers to a well‑known figure in Greek culture — a household servant responsible for raising the child, teaching them the rules, virtues, and expectations of the home. In other words, the guardian enforced the law, shaping the child’s behavior until maturity.

Now Paul’s point becomes clear: If you want to live by the law, you will die by the law. But if you live by grace through faith in Christ alone, your salvation is secure.

And even more, Paul says that in baptism “you have put on Christ.” This means Christ is now your garment — your covering. When God the Father looks at you, He sees Christ. This is the gift given to you in baptism, by the power of the Holy Spirit, through the promise of God’s Word (Rom 10:17).

If I have not made it clear up to this point, allow me to reiterate: your subjective feelings do not determine your salvation. When you trust and believe that Christ is enough, then your salvation is secure — not because of the strength of your faith, but because of the strength of the One your faith clings to. Your faith has an object, and this is Christ.

Even when you feel like you aren’t doing enough… Even when you feel spiritually dry… Even when you feel like you’ve failed again… Even when you feel unworthy…

Your feelings do not get the final word.

We all struggle with this. It’s real. It’s human. It’s part of living with a sinful nature.

But when that water covered you in the Triune Name of God, you were given something objective — a promise outside of yourself for the forgiveness of sins by faith in that promise. The grace given to us by Christ alone, through faith alone, is what saves. And this is the objective truth God gives us in Scripture for our assurance.
