What does it mean to be a soldier of Christ?

Christians are called to be soldiers of Christ, which entails actively participating in the spiritual warfare against sin and darkness. This image emphasizes the seriousness of the Christian life, requiring believers to don the armor of God and engage in battles for truth, righteousness, and the souls of those ensnared by sin. Just as soldiers train and sacrifice for their earthly goals, Christians must be prepared to endure hardships while seeking to expand Christ's kingdom, all while relying on His strength and guidance throughout their mission.
