In heaven there are not guns, knives, bombs and samurai swords to execute any judgment. These belong to the physical realm. The waepons with which Jesus fights are not of the world! On the contrary they have divine power to demolish strongholds.(2. Cor. 10:3-5).
Note that not alone Christ is fighting against the demons but we men on earth according to Ephesians 6:12, we are putting on the armor and fight! "For our [daily] struggle is not with flesh and blood but with the principalities, with the powers, with the world rulers of this present darkness, with the evil spirits in the heavens"
Already since Paul wrote Ephesian 6:12 about the armor of God Christians have learned to fight and are leading this spiritual battle, Christ fighting in the battle in the first line.
Jesus' weapons in the spiritual warfire against the demons therefore are since 2000 years:
Fighting with TRUTH,
RIGHTOUSNESS;
GOSPEL OF PEACE (not Armageddon)
Word of God,
Prayer.
Therefore, put on the armor of God, that you may be able to resist on the evil day [everyday that passed over the last 2000 years!] and, having done everything, to hold your ground. 14 So stand fast with your loins girded in truth, clothed with righteousness as a breastplate, 15 and your feet shod in readiness for the gospel of peace.16 In all circumstances, hold faith as a shield, to quench all [the] flaming arrows of the evil one. 17 And take the helmet of salvation and the sword of the Spirit, which is the word of God. (NABRE)
So tell me anybody, where the hell Jesus is fighting here. We alone have to armor us and to fight, Christ help us though. Let me smith my Smurai Sword for any case.
