The Armor of God, Conduct in the Campaign & Implementing the Victory of Christ in our Lives: OT Examples of SPIRITUAL WARFARE: PART 1 of 5

We can derive from Old Testament passages the truth of God’s faithfulness, even when Israel herself proved faithless; God would not deny His Word, particularly where the Abrahamic and Davidic Covenants were concerned.
So likewise we as Christians have every reason for the hope granted to us by a faithful and Almighty God!

We as the church can look back in hindsight and learn from their examples, both in the positive and negative sense.
Old Testament examples of warfare were primarily physical in nature with sword and shield (i.e. historical wars conducted by the armies of Israel), whereas the church is admonished to fight their campaigns with spiritual, rather than with carnal (physical) weapons (2 COR 10:3-5; EPH 6:10-18).

The ARMOR and IT’S ACCOMPANYING PARTS: Part 7 – Section 4: The Helmet of Salvation:

The Spirit of God represents a kind of spiritual software and an anti-virus ‘program’. I looked up the term ‘anti-virus’ and found this interesting definition:

“A software program written so that on execution (this is usually automatic on boot up) it scans the hard drive and related processors to identify, isolate, and eradicate the virus.”

Interesting words: identify, isolate and eradicate! They are fraught with all sorts of spiritual meaning and ramifications.
Scripture and conviction by the Holy Spirit in identifying the virus known as sin in our lives as believers is necessary before any sanctification can take place. Isolation of sin, by means of “being separate” from such in our hearts, that is a repudiation of sinful thoughts and tendencies is what’s required once such viral contaminates are identified. Eradication is only possible by reckoning (accounting it to be truly so) ourselves to be “dead to sin” and looking to the Cross for its availing power and letting ourselves die to sin and its preceding temptations.
