It is crucial for every Christian to understand that he/she is in a mighty Battle for the Mind. This protection is not available to someone who is not a Christian. You have to be a child of God and have received salvation. You cannot get around it as a Christian you must have perseverance, preparedness, and weaponry to win this battle.
The Romans helmet was needed and a total part of his armor. It had obvious use it protected the head of him as a soldier. Today there are many helmets but they perform basically the same functions. As believers, our helmet of Salvation comes from God Himself. This battle is on a spiritual level and all done with spiritual weapons, not human weapons. To win this battle and be victorious we must stand in His weapons without doubting. We must put on the Full Armor of God.
If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him. But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed. For let not that man think that he shall receive any thing of the Lord. A double minded man is unstable in all his ways. James 1:5-8
We can not fight with worldly philosophies, persuasive words of human wisdom, human wit, rationalism, entertainment, skills, reasoning, and ideas these won’t win the spiritual war. Fasting and prayer can build your faith to help you in this battle.
Hebrews 10:22-23 let us draw near with a sincere heart in full assurance of faith, having our hearts sprinkled clean from an evil conscience and our bodies washed with pure water. Let us hold fast the confession of our hope without wavering, for He who promised is faithful.
This is a battle of the mind and heart the devil comes after us he is like a roaring lion and he wants to devour you.
Be of sober spirit, be on the alert. Your adversary, the devil, prowls around like a roaring lion, seeking someone to devour. But resist him, firm in your faith, knowing that the same experiences of suffering are being accomplished by your brethren who are in the world. After you have suffered for a little while, the God of all grace, who called you to His eternal glory in Christ, will Himself perfect, confirm, strengthen and establish you. 1Peter 5:8-10
The thoughts drive what we do and are actions that come from them. Our thoughts are essential as we serve the Lord it is very critical that our thoughts are protected. These are critical in spiritual warfare you have to be mindful or you will have a very tuff time.
(2 Corinthians 10:3-5)
For though we walk in the flesh, we do not war according to the flesh, for the weapons of our warfare are not of the flesh, but divinely powerful for the destruction of fortresses. We are destroying speculations and every lofty thing raised up against the knowledge of God, and we are taking every thought captive to the obedience of Christ,
