What does the Bible say about the spiritual warfare Christians face?

Spiritual warfare is a recurring theme throughout Scripture, illustrating the ongoing battle between good and evil. Christians are warned that our struggle is not against flesh and blood but against the rulers, authorities, and powers in the spiritual realm (Ephesians 6:12). This warfare is evident in the experience of believers like Jacob, who faced the threat of Esau and the dangers of the land. The assurance is that angels are tasked by God to protect and minister to His chosen ones, helping them fight this unseen battle. The victory, however, is ultimately assured through Christ, who has already defeated the enemy.
