A true believer having a Spirit-controlled life can be sure to be in a spiritual war. Ultimately, Satan’s power over Christians is already broken, and the war is won through the crucifixion and resurrection of Christ. However, in life on earth, battles of temptation go on regularly. The Lord’s power, the strength of His Spirit, and the force of biblical truth are required for victory.
The armor should be the sustained life-long attire. Satan’s deception and schemes are carried out by his demons and are highly structured for destructive purposes. Satan wants us to distrust God, forsake obedience, have doctrinal confusion, falsehood, be hindered in service, be divided, serve in the flesh, live hypocritically, be worldly, and reject biblical obedience in any way.
Belt – Pulls spiritual loose-ends together in truth – tucks away anything that hinders – Self discipline in devotion to victory;
Breastplate – The Christian’s chief protection against Satan and his schemes. As believers faithfully live in obedience to and in communion with Jesus Christ, His own Righteousness produces in them the practical, daily righteousness that becomes their spiritual breastplate. Lack of holiness leaves them vulnerable to Satan;
Shoes – It is knowing that through Christ, believers are at peace with God, and He is on their side – confidence of Divine support allowing the believer to stand firm.
Shield – Basic trust in God – the necessary, continual trust – trust in God’s Word and Promise – all sin comes when the victim falls to Satan’s lies and promises of pleasure, rejecting the choice of obedience and blessing;
Helmet – Not attaining salvation, but protection against Satan’s weapons of doubt and discouragement to destroy a believer’s assurance – salvation is eternally protected, and one need not fear its loss.
Sword – God’s Word – the only needed weapon – infinitely more powerful than any of Satan’s. Used defensively to fend off Satan’s attacks, and offensively to destroy his strategies.
