Why is it important for Christians to engage in spiritual warfare?

Christian life involves constant spiritual warfare against adversaries that seek to undermine our faith. Paul emphasizes the necessity of this struggle in 2 Corinthians 10:5, where we are to bring every thought into captivity to the obedience of Christ. This warfare helps believers discern truth from falsehood, particularly in a world rife with false teachings and ideologies. Furthermore, by participating in this battle, we uphold the truth of the Gospel, spread the message of grace, and protect the integrity of the Church against influences that may dilute its mission.
