What does 1 John 5:4 mean?
John returns again in this verse to the theme of believers as overcomers. Jesus cannot be overpowered by darkness (John 1:5), and has defeated the powers of this world (John 16:33). Believers are not to be overcome by evil, but overcome evil with good (Romans 12:21). Believers have overcome both the evil one (1 John 2:13–14) and evil spirits (1 John 4:4). Christians are not left weak and defenseless in spiritual battles. On the contrary, those battles are already won, by Christ.How do believers overcome the world? Verse 5 gives a more direct explanation: by believing in Jesus as the Son of God. Here in verse 4, John simply refers to "faith" as our victory. The faith of the believer is the victory that overcomes. Every believer is an overcomer and is victorious because they have eternal life in Christ (John 3:16) and abundant life now (John 10:10). God's Spirit lives within the believer to provide power over the battles of this world.
