Why is it important for Christians to be wise and brave in spiritual battles?

In 2 Samuel 10, both Joab and David demonstrate wisdom and bravery in the face of adversity. For Christians today, this serves as a reminder that believers must be equipped to face spiritual battles with discernment and courage. The weapons of our warfare are spiritual, requiring us to be rooted in Scripture and dependent on God's strength. As the apostle Paul instructs, we wrestle against principalities and powers, thus necessitating a mindset of readiness and vigilance. It is essential for Christians to embody this spirit of bravery and wisdom, trusting that God is with them through every struggle as they witness for Christ.
