The weapons we fight with are not the weapons of the world.

2 Corinthians 10:4-5 - " The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ."

Ephesians 6:12 - " For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms."

As we look at all the terrible things that are happening in the world today, and all the injustices taking place, we must keep in mind that the battle is not with people, administrations or government authorities.  These are only exterior actions being played out by people who don't have the mind of the Spirit of God. The evil we see is the result of an inner sickness, which is sin. Man is innately sinful, and the powers of darkness (Satan and the fallen angels) use this to their advantage to rack havoc in the world. John 10:10 - "The thief comes only to steal and kill and destroy; I have come that they may have life, and have it to the full" 

As believers we are to speak out against the evil of these days, and take practical actions to fight injustices and work to help improve our world. Yet, we must keep in mind this is not where the true battle lies. The true battle is a spiritual battle. We must come against the thoughts (lies) that are spewed forth by the enemy, Satan. We must fight against the unclean (demonic) spirits that are influencing our society to disobey God and not walk in love.

What are the spiritual weapons needed for this struggle?

Ephesians 6 speaks of several weapons at our disposal as believers.

We are to stand firm in truth. This means living in the truth and speaking the truth. We are to live righteous lives, and speak out against unrighteousness. We must be rooted in the Gospel of peace, and proclaim it to others. We must walk and speak faith. We must be grounded in the Word of God, and speak the Word of God, which is wielded by the Holy Spirit. You may notice that the battle is greatly dependent on our stance or position in Christ. It is more about being whom we should be then doing. As we stand well in Christ, and be obedient to Him, Christ will do the heavy lifting. He is the strong man in the battle. 

2 Chronicles 20:15 - " He said: “Listen, King Jehoshaphat and all who live in Judah and Jerusalem! This is what the Lord says to you: ‘Do not be afraid or discouraged because of this vast army. For the battle is not yours, but God’s."

If you delve into this story you will find that the battle was won through prayer, praise, faith and obedience of the people of Israel. Yet, it was God who won the victory.

Finally, we are to pray continually for ourselves and others. This is where the  battle is fought in the spiritual realm. There are many references in the Bible that show us that God seeks and depends on out participation in the battle through prayer. 

Acts 12:5-6 - "So Peter was kept in prison, but the church was earnestly praying to God for him.
The night before Herod was to bring him to trial, Peter was sleeping between two soldiers, bound with two chains, and sentries stood guard at the entrance. ⁷ Suddenly an angel of the Lord appeared and a light shone in the cell. He struck Peter on the side and woke him up. “Quick, get up!” he said, and the chains fell off Peter’s wrists."

We must be continually in prayer for ourselves and others.
