Day 1: The Unchangeable God

Facebooktwitterpinterest
Introduction
All of us have been there. Some of us are there right now—staring at a mountain of bills or a pile of unresolved struggles, wondering how we’re going to make it. You know the “right” answers. You know God is faithful. You know you shouldn’t doubt. And yet the questions still whisper:

Does God actually care about me? Will He help me get through this? Is His faithfulness real, or am I imagining it?

If that’s where you are, you’re not alone. God’s people have always known the reality of doubt. But while doubt may be part of how faith grows, we can’t afford to let it linger unchallenged. Over the next 30 days, we’re going to confront doubt with truth—not simply so you feel better about your circumstances, but so the doubts that rob you of confidence in God’s promises lose their power.

We often treat the resurrecton as a surprise ending to Jesus’ story, a “happily ever after.” But the resurrection is far more than that. It is a spiritual and legal necessity for our salvation. Jesus didn’t just die—He rose. And in rising, God handed you a “receipt” stamped “Paid in Full,” proving that your forgiveness has been accepted. The resurrection also reminds us that we don’t worship a memory; we worship a living Savior who intercedes for us even now.

And the same power that raised Jesus from the dead is at work within you. Every stronghold, every fear, every doubt—none of them stand a chance against resurrection power.

Here’s where we’re headed:

  • Week 1: Meet The Architect—the God who planned the rescue.
  • Week 2: Silence the “Saturday lies” that whisper God has abandoned you.
  • Week 3: Find faithfulness when life feels like a shadow.
  • Week 4: Walk in the power of the Risen Life. Bring your doubts—even the ones kicking and screaming—into the light of resurrection truth. Will it be easy? Probably not. Will it be good? Absolutely. Let’s begin Week One by meeting the Architect of the Tomb.
Day 1: The Unchangeable God

Scripture: Malachi 3:6: “For I the Lord do not change; therefore you, O children of Jacob, are not consumed."

We live in a world that is constantly changing. From the latest phone model you have to the shoes you wear, things do not stay the same. Styles come and go. Technology quickly becomes outdated and is replaced. Just when you get used to something, it changes, and you have to adjust again. Given the ever-changing world that we live in, it makes sense that there is a degree of uncertainty to so much in life. I know you know this. But do you ever wonder, “Will the Lord change his mind about me today?”

In Malachi, we meet the unchangeable God. What we mean by this is that his character, essence, promises, and purposes do not change. Now, the immutability (his unchanging nature) of God may seem to be a strange place to begin as we proceed on this journey of destroying our doubts. Why not start with his love or mercy? Why does it matter that we encounter the architect of the empty tomb as the unchanging God?

The unchanging nature of God provides the secure and sure foundation for our faith. Unlike people and things who change in goodness and perfection, God does not. He can never be more loving, good, merciful, or powerful than He is right now. He doesn’t have “off” days in which you are no longer His favorite child. There is never a time in which He looks back at you with regret. The people in Malachi’s day needed to encounter the unchangeable God just as much as we do, especially as He was preparing to purify them because of their sins.

Therefore. This word provides tremendous hope to the doubters. Why? Because something is going to follow it that leads to a sure hope. You aren’t consumed because you held so tightly to God. No, you aren’t consumed because He is unchanging and refuses to let you go.

These people needed to know that their changing and fickle nature was not going to thwart the purposes of the Lord. Why can they have hope in uncertain times? Because the Lord does not change in who He is. What is their sure and steady foundation when the world seems to crumble beneath their feet? The unchangeable God.

Doubt thrives on the diet of “what if’s.” What if God can’t take any more of my sin? What if God doesn’t care about me? What if He takes away everything that is important to me? Don’t miss how Malachi 3:6 is a knockout punch against this kind of doubt. These children of Jacob were not consumed because they were good. No, they were not consumed because God is unchanging.

This unchangeable God is the grand architect of the empty tomb. Jesus comes on His great rescue mission, but is killed, and hope is seemingly placed into the ground. What those who killed Jesus hadn’t counted on was the immutable God who guarantees the safety and protection of His people, as He demonstrates His reliability by raising Jesus from the dead.

Other people may (and do) have second thoughts about you, based on how you act. Many of us worry that if we blow it on one day, those closest to us will push us away. So, we act as if we always have to be enough, and can never fail. We start to doubt how God can be good and His plan sure when life is this hard to keep up. What we need is the reminder from the architect of the empty tomb that His thoughts towards us never change. He doesn’t start getting second thoughts about us. The resurrection is proof that He will keep all His promises to us.

Others of us quietly doubt how God views us in those times in which we sin, especially when we sin really badly. Our lack of faith creeps in, and we imagine He really doesn’t want that much to do with us. The consistent and unchanging nature of God assures our doubting hearts that He is still very much for us.

And still others of us have the tendency to cling to things that we think we can trust a little more than God. These things can include our own understanding, performance, position, or accomplishments. Or they may include aspects of creation that lure us in to believe that they are more comforting and reliable than God himself. But if God could change, we would never be fully sure of our salvation. What if God decided on a different plan?

The resurrection provides the evidence of His unchanging nature and God’s ability to fulfill His plan. Do you fear death? Death, for many, is the ultimate fear. The resurrection shows us that nothing is too dead for God. That relationship you’ve been trying to save? That health or financial challenge you are trying to navigate? Even when it seems as if all hope is lost, there is nothing too dead for the Lord. God is not falling down on the job in any way. Our passage today in Malachi reminds us that God is not reacting to our lives. Your failure from yesterday and my failure did not stop His plans. You and I are resting on the Rock of Ages who will never falter or fall.

Many of you have walked through a construction site and know how messy it is. There is dust, noise, and piles of debris. If you didn't know any better, you might be tempted to think that the builder doesn’t know what He is doing. In a way, this is what doubt feels like. We look at the mess of our unanswered prayers and start thinking that everything has fallen apart.

But Malachi 3:6 reminds us that the master architect is still in control. He doesn't look at the mess of your life and decide to build something cheaper or easier, because you are too much work. No, because He is immutable, His plans for your good and salvation are secured and sure.

As you look towards the resurrection, remember today how it stands as the eternal proof that even when the plan looked its worst with a cold tomb and a dead Savior, that the architect’s ultimate plan hadn't shifted an inch. May this truth ground you today.

  1. We live in a world of "planned obsolescence" and "cancel culture," where people and products are replaced the moment they stop performing. How does this constant change make it harder for us to trust that God won't reevaluate His commitment to us when we have a bad day?
  2. If God could change His mind based on our performance, how would that specifically fuel the doubts you are currently facing?
  3. Why is God’s unchanging nature the only thing that makes the Resurrection "legal proof" of our salvation? If God’s character could shify even 1%, why would the empty tomb lose its power to comfort us?
List 3-5 things that are currently causing you doubt or stress, such as a fluctuating bank balance, a strained relationship, or a health scare. Put these on the left side of a piece of paper and draw a line in the middle.

Then on the right side, label it "The Bedrock." For every item on the left, write down a specific attribute of God from Day 1 that cannot change (e.g., His promise to provide, His finished work on the cross, His presence that never leaves). Whenever a doubt from the left side whispers to you today, "What if this fails?", answer it with the truth from the right side: "This might change, but the Architect does not."
