What does the Bible say about the whole armor of God?

In Ephesians 6:11, believers are commanded to put on the whole armor of God to withstand the attacks of the devil. This signifies our vulnerability; without the armor, we cannot stand firm in spiritual battles. Paul elaborates that this armor comprises several parts, including truth, righteousness, faith, and salvation, which all point to God as our source of strength and defense against evil. The armor is not merely a metaphor but a concrete representation of how we should approach spiritual warfare with the protection that God Himself provides.
