I was in the choir room with the choir warming up for our anthem just a few minutes ago. Sarah asked if anyone had accidentally picked up her reading glasses from the piano. Kathy, who'd just been sitting at the piano and was holding a pair of reading glasses in her hand said, "No. I promise. these are my reading glasses." Kathy's sister, Sally, said, "Uh, Kathy. You have a pair of reading glasses on your head!" Sure enough, she did! And they were the exact same style as Sarah's! Kathy Said, "I'm losing my mind!" We all had a good laugh.
We use that expression, "I'm losing my mind," as a bad thing. But the truth is, if we follow Christ, we are losing our old mind and Christ is giving us a NEW mind. And that's what I want to talk about today.
1And so, dear brothers and sisters, I plead with you to give your bodies to God because of all he has done for you. Let them be a living and holy sacrifice—the kind he will find acceptable. This is truly the way to worship him. 2 Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God’s will for you, which is good and pleasing and perfect.
3 Because of the privilege and authority God has given me, I give each of you this warning: Don’t think you are better than you really are. Be honest in your evaluation of yourselves, measuring yourselves by the faith God has given us.
Explain the Passage
The Apostle Paul gives us the image of a sacrifice placed on an altar. At the time Paul wrote, animal sacrifice was a common religious practice—for both Jews and Gentiles. A living animal was usually placed on an altar, its throat cut so the blood would drain out along with the animal’s life. Then the animal would be butchered, cooked over fire, and eaten, or completely incinerated with fire. As you can imagine, it was a startling thing to behold—something that left a lasting impression. The point is a sacrifice was complete and irrevocable. Right? You can’t make half a sacrifice. You can’t make a sacrifice and then take it back. It’s an all or nothing proposal. (At least for the animal!)But Paul turns the tables on us. He invites us to leave the animals alone. Instead, he urges us to put our life on the altar. Give your own body—all that you are—as a living sacrifice. It’s not human sacrifice he is asking; it’s self-sacrifice. It’s surrendering all that you have and all that you are to the will of God. It’s an “all-in” whole-hearted proposition that is true worship—truly pleasing to God—and it changes everything.
It’s what Jesus did for us, you see. Christ gave himself completely for us on the cross. He didn’t just do some good things. He didn’t just preach some great sermons. Jesus gave everything. He was whole-heartedly committed to God’s plan of salvation for you. He willingly sacrificed his entire life for you—even when it meant dying on a cross.
And Christ’s sacrifice makes it is possible for us to be made NEW! We can have NEW desires, a NEW way of thinking, a NEW purpose in life, NEW peace and joy and confidence, and ultimately the promise of eternal life with a NEW heaven and a NEW earth. But in order for the NEW to come, we have to let the old die. In fact, we have to trust Jesus enough to place our old self—our old ways of thinking and living—on the altar as a sacrifice. For when you sacrifice our old life, Jesus will make you NEW!
The key verse for us today is verse 2a – Don’t copy the behavior and customs of the world, but let God transform you into a new person by changing the way you think. Most of us grow up copying the behavior and customs of the world. We do the things people around us do because we think the way they do. In fact, if we ever see someone who acts or thinks in a way that in noticeably different, we might even call them weird. I know when I was in high school, I had a few friends who lived out their Christian beliefs very faithfully. At the time, I thought they were very weird because they didn’t act and talk and think the way most high school students did. They stood out. They were “weird.” At the time, I thought they should just “copy the behavior and customs” of everyone else. Now I see they were the minority that was really doing what God wanted. Now I wish I had been part of that minority when I was in high school. Now, I am—or at least I am striving to be—because I am striving to let God transform me into a NEW person. So what if it makes me different. So what if it makes me weird. If it makes me more like Christ, great!
We all need to let God transform the way we think. Romans 12:3 says, “Don’t think you are better than you really are. Be honest in your evaluation of yourselves, measuring yourselves by the faith God has given us.” So let’s apply this wisdom and think clearly and honestly about ourselves.
First of all, you are not the center of the world. Regardless of what the unbelieving world insinuates, the world doesn’t revolve around you. You are not entitled to “Have it your way.” Your own personal happiness is not the chief goal in life. In fact, if you faithfully follow Christ and live for God the way He intended for you, you will definitely need to give up some things you want. It is a sacrifice. (Remember how our scripture said to sacrifice yourself to God?) Following Christ means letting go of our selfish desires, our self-centered motives, and serving others instead of ourselves. This is tough for many people, but we need to let God transform our way of thinking.
Some people think too highly of themselves. Others struggle with thoughts that they are not important or that they are not good enough. That’s why I like Romans 12:3 so much. It addresses both misunderstandings. It says, “Be honest in you evaluation of yourself.” And the Truth is, (though you are not the center of the world) you are very important to God. God deeply loves you. He has been working out your salvation since the beginning of time. He cared enough to send Christ to die for you. God wants you to be part of His mission to save the world. That’s pretty impressive. You must be important! So if you struggle with low self-esteem, let God transform the way you think. You are precious to Him.
Do you struggle with shame or guilty? God has promised He will forgive you if you ask. No matter what you’ve done—how big or how small—God will forgive you. 1 John 1:9 says, “If we confess our sins to him, he is faithful and just to forgive us our sins and to cleanse us from all wickedness.” Shame and guilt can cripple us. It makes us hesitant in our relationship with God and others. Shame and guilt are constant burdens that weigh us down and slow us down in our spiritual life. They sap the joy God wants us to have. They can make life weary and full of worry. So if you struggle with shame or guilt, let God transform the way you think. The truth is, forgiveness is available through faith in Christ. And if you believe, God does not think about your sins anymore. They have been washed away. God says in Isaiah 1:18, “Come now, let’s settle this,” says the Lord. “Though your sins are like scarlet, I will make them as white as snow. Though they are red like crimson, I will make them as white as wool.” If you asked God to forgive you, He has. Now it’s time for you to let go of your thoughts of shame and guilt. Let God transform the way you think.
Some of you may struggle with doubt. The unbelieving world says this world is all there is. Since science cannot verify the existence of an afterlife, they reject the idea as a fantasy. Since they cannot see God, they reason He is just a myth. But faith helps us see that there is more to life than just what you can see and hear and taste and touch. Faith helps us to know that Truth is more than just facts and figures. Faith helps us to see there is always hope even when all seems to be lost. Faith helps us to know that the future is ultimately in God’s hands and so, there is nothing to fear. Faith helps us to hear God’s still small voice leading us down the right path. Faith helps us to feel God’s presence when we need assurance that everything is going to be alright. Even if we lose this life, God has another waiting for us in Eternity. And all the wrongs of this world will ultimately be made right one day. It’s OK to have questions. It’s OK to have doubts. Sometimes they lead us to deeper understanding and faith. But if your doubts control you or keep you frozen with fear, maybe it’s time to let God transform the way you think. “For God has not given us a spirit of fear and timidity, but of power, love, and self-discipline.” (2 Timothy 1:7) Take hold of the power, love, and self-discipline God wants you to have. Let Him transform the way you think.
ConclusionAs I close, I join with the Apostle Paul and plead with you, give your bodies to God as a holy and living sacrifice. Don’t hold anything back. Surrender yourself completely to the Lord and He will transform your mind.
