How do we know the necessity of spiritual warfare?

The need for spiritual warfare is rooted in the understanding that Christians are part of a cosmic conflict against principalities, powers, and spiritual wickedness in high places, as mentioned in Ephesians 6:12. This battle began as early as the Garden of Eden and is ongoing, impacting believers today. Christians must recognize that their true struggle lies not against other human beings but against malign spiritual forces intent on destroying their faith. Understanding this necessity compels believers to be vigilant and to actively wear the spiritual armour God has provided, thereby ensuring they are prepared to confront these formidable adversaries.
