There’s a difference between real and fake Christianity. And this litmus test, given by the Apostle Paul in Romans 8, shows where you stand. Your mind is either: (1) set on the spirit or the flesh; (2) set on life or death; and (3) subject to the law of God or in hatred to it. That’s why there’s no such thing as a “gay” or “thieving” Christian. If you’re a true believer, you will denounce such sins and put them away. You know who you are by what rules you—be it the spirit or the flesh.

Today on social media, you can be accused, tried, condemned, and sentenced all in one day. Yet this is light compared to the devastating condemnation of Almighty God. The good news is this: “There is therefore now no condemnation to those who are in Christ Jesus” (Rom. 8:1). Redeemed sinners are freed from God’s wrath and eternally secure in Him. So, if you’re a believer, praise God that nothing will be held against you when you reach the Final Judgment. Though Satan accuses you day and night, you can live in freedom, for Christ has paid your debt!

God created everything from top to bottom in our lives that Jesus Christ would be preeminent (Col. 1:17-18). This includes marriage. Put simply, the preeminence of Jesus Christ is the greatest secret of a happy marriage and a happy home life. But what does it look like to make Jesus Christ the center of your marriage? First of all, devote yourself to his preeminence. Second, count all things as loss for the sake of Christ. Third, behold the glory of Jesus Christ daily in your life together. And, finally, set your minds on the things that are above, where Christ is seated at the right hand of God.

In this life, the Christian will always be dealing with sin. This side of heaven, there’s no sinless perfection. God’s good and holy law is a tool that reminds us of this reality. It is a searchlight that shows us who we really are, as we deal with remaining sin that still wars within us. This rightly frustrates the believer, as we battle wrong impulses that persist. Yet we need not despair—though we’re commanded to keep God’s law, those who are in Christ are not condemned by it, for He has paid for all our sins. The law and the gospel thus work together to encourage believers to rest in Christ’s work for them.

What does it mean to make Christ the center of your marriage? Husbands and wives cannot write their own lines. They have a role to play. Marriage was designed by God to paint a picture of Christ’s love for the church, and the respect of the church for her Savior. A husband’s role is to be like Christ, and a wife’s role is to be like an adoring church who loves her husband. So when you get up in the morning, what kind of picture are you painting when you roll over in bed and see your spouse? When you have breakfast together? When you contact one another throughout the day? Let it be a glorious and beautiful picture of Christ and His church!

How should Christian’s engage with God’s law? The truth is, the believer’s relationship to the law of God will have massive consequences in your life. It will either make you a legalist, or it will make you one of the blessed of the earth. For the Christian, the condemning nature of the law has ceased. But the commanding power of the law continues, and the Bible makes it clear that the believer is always happiest when he is under its consultation. Why? God’s law is a rule of life that teaches you how to live, and when believers keep His law, He promises great blessing.

Every word in the Bible is the word of Christ. This includes the 613 Old Testament laws and the 1050 laws and commands found in the New Testament. But how are we as Christians to interpret them? It starts by understanding God’s four central purposes for the law: (1) To disclose His character and righteousness; (2) To reveal and convict us of sin; (3) To constrain evil in the personal and civil realm; and (4) To give us a rule of life. To this Scott Brown adds nine key questions to ask, including: Is it a moral, ceremonial, or civil law, and how is it fulfilled in Jesus Christ?

How can Christians be “dead to the law” if the law is “holy, just and good” (Rom. 7:4, 12)? Scott Brown answers this thorny question, putting Romans 7 in proper context. The Apostle Paul uses the metaphor of a woman whose husband dies, who then is free to remarry, being no longer bound by the law of her first husband. Being married to Christ is akin to this. When He regenerates us, we are married to Him and dead to the condemnation of the law, our old husband, which once condemned us. Now our “Maker is [our] husband” (Isa. 54:5), who helps us to freely keep His good law rather than be crushed by it due to our sin.
