Spiritual Warfare – The Battle Within Me

The first section of the sermon presents the theme of spiritual warfare as an unavoidable reality in the believer's life. The pastor identifies three main enemies: the world, the flesh, and demons; among which sin in the flesh is identified as one of the most dangerous adversaries. The sermon is based on Romans 7:14-25 to illustrate that even the great apostle Paul faced this internal battle. The fact that Paul himself experienced temptation and stumbling offers hope to believers that they are not alone in this struggle.

The second section develops the theological argument through analysis of Robert Louis Stevenson's novel Dr. Jekyll and Mr. Hyde. The pastor shows that every person has two natures: one virtuous with conscience, and one completely evil and depraved. Stevenson, a Christian believer, directly quoted Romans 7:14 in his work. The character of Dr. Jekyll represents the person who respects the law but still carries darkness within, while Mr. Hyde represents the person completely dominated by sin. The story demonstrates that the evil nature is never truly eliminated but only concealed, waiting for an opportunity to awaken. The pastor emphasizes that Mark Twain said "everyone is a moon and has a dark side which he never shows to anybody."

The third section applies the message to believers' understanding of sin and salvation. The pastor clarifies that the purpose of the law is not for perfect obedience but to expose sin in the flesh. The best person will see their own shortcomings more clearly when approaching God, just as Paul confessed himself to be the chief of sinners despite dedicating his entire life to Christ. The sermon warns believers against boasting in their moral living or comparing themselves with others, for whoever keeps the whole law but stumbles in one point is guilty of all. The pastor lists catalogues of sins from Scripture to prove that no one can be completely blameless.

The fourth section emphasizes that we cannot save ourselves through personal determination or willpower. Paul desired to do good but found himself doing evil, causing him to cry out in despair. However, the sermon concludes with good news: only through Christ and His Holy Spirit can we be delivered from the burden of sin. Not through additional knowledge or effort, but through God's power. This is a transition from despair to hope, from self-reliance to serving God.

The fifth section expands the application with history and practical examples. The pastor cites the example of Prohibition in the United States (1920-1933), when the law banning alcohol was enforced but failed to achieve its moral goal and instead created more crime. This illustrates the principle of Romans 7:7-8 that the law often awakens what it seeks to prevent. The sermon's conclusion is powerful: only Christ through His Holy Spirit can deliver us from this body of death.
