In spiritual warfare, believers battles against his/her flesh as well as demonic spirits in their lives to follow Christ. Every believer, before the redemption of their bodies in that final day, still possesses a sin nature. From our sin nature, evil desire arises within us and the believer is tempted to sin. Each believer is called to spiritual warfare to battle against our fleshly desires (James 1:13-15, 1 Peter 2:11).
The spiritual warfare also exists in the demonic realm against believers (Ephesians 6:10-20). We see examples of demonic spirits moving people, circumstances, and even indwelling unbelieving people to deter people from following God. However, born again believers cannot become demonized (possessed or influenced by demons from within) due to the presence of the Holy Spirit within the believer (2 Corinthians 6:14-18, Colossians 1:13, 1 John 2:13-14, 1 John 4:4 and 1 John 5:18). Though believers cannot become indwelt by a demon, they can become tormented, oppressed and harassed externally by demons through various spiritual attacks, which can be overcome by believing on to the gospel truth, and putting on the armor of God (2 Corinthians 12:7, Ephesians 6:10-20).
