Ephesians 6:13 (NET), “…take up the full armor of God so that you may be able to stand your ground on the evil day, and having done everything, to stand.”
In order to stand firm, you must fasten “the belt of truth around your waist.” That means you study the scriptures daily. Learn the plan of GOD so you will not be swayed by errors or church traditions. John 4:24, “God is a Spirit: and they that worship him must worship him in spirit and in truth.
The breastplate of righteousness protects your vital organs from deadly injury. It is the breastplate of Christ's righteousness – his merit covers our life, our vitals. Our own righteousness is “as filthy rags.” (Isaiah 64:6) But “through faith in Christ, the righteousness from God that depends on faith” covers and protects us. Philippians 3:9.
Your feet are sandaled with readiness for the gospel of peace.

Unless you have an intellectual apprehension of the truth – a helmet – the enemy will strike you with arrows of bitter words, sarcasm, deception, and lies. You “are kept by the power of God through faith for salvation,” 1 Peter 1:5.
The sword is the only item that is not for defense but for attack. Look how Jesus dealt with Satan after 40 days of fasting in the wilderness. He countered Satan with scriptures – “It is written”. We need to know the Bible very well so we can quote scripture when someone is attacking the truth. Matthew 4:1-11
The war with Satan is a spiritual war which requires spiritual armor. 2 Corinthians 10:4-5 (NKJV), “For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God…”
