Many believe that it is their role to “put on the whole armor of God” and engage the enemy daily. But, these same people fail to recollect that satan is already a defeated foe, Jesus vanquished him at Calvary. For those who relate to the Bible being written in terms reflecting agrarian lifestyles, by analogy you are not obliged to conquer and cultivate the land as much as being responsible for maintaining, and harvesting the fields already bequeathed to you.
This does not mean that the world and its evil will readily yield to your authority. Rather, it will resist you with words and deeds, striking at you as ferociously as it is able. Thereby, per Ephesians 6:11-14, you are encouraged to stand, defend, resist, and claim (vocalize your belief) that in Jesus’ name your victories (prosperity in every manner needed and desired) already exist (per prior petitions – Mark 11:23-24, Matt 7:7-8).
So, when the defeated foes attack you (and yours) physically, mentally, emotionally, financially, or question your spiritual zeal, stand your ground, with praise and thanksgiving, declaring “I am (we are) already blessed in Christ!” and the supplies will be there if you believe what you say. You are not fighting for victories, rather, you are standing in the wake of Jesus’ victories.
