For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. (Eph 6:12 KJV)

The apostle does not deny that we are fighting with flesh and blood too, that is with devious, godless and fiendish people, who are opposed to the kingdom of God and against the Lordship of Jesus Christ. However if we were just in struggle with these, then it would be an even match between human beings and not so dangerous especially with godly help on our side. However the apostle teaches us here, that we are called into a much more perilous combat, because the fallen angels are our foes. In this situation is makes no difference if this or that person doubts the existence of these heavenly creatures and spiritual beings. The apostle address invisible principalities and powers that  actually have joined the final struggle for dominion of the universe. The heroes and valiant battalions face each other and its going to go right down to the wire. They have the advantage of seeing us, whilst they are totally invisible on our side. It’s quite intimidating to know that you are surrounded by such imperceptible hosts.  The fear and danger are further heightened by the terrible power of the enemies. The apostle calls them “rulers of darkness of this world” and “principalities” in “high places”. The Christian congregation better be alert and expect an onslaught at any time: Be awake and on your guard!

O God, heavenly Father! You know the peril facing your congregation and Church. Without your help we are lost. We can’t stand alone against the rulers of darkness. Therefore o Lord and God keep and preserve us steadfast in your Holy Word, strengthen our faith and trust in you, so that we may fight valiantly against the wiles of the devil and with your aid attain the final victory. We ask this in the name of our Lord and saviour Jesus Christ, who lives and reigns with you and the Holy Spirit now and forever. Amen.

You hellish pack of evil foes, get off, you’ve nothing to say right here. This house belongs in Jesus’ reign, let it rest and sleep in peace. The angels mighty watch keep it safe and sound. Their mighty hosts are keeping guard. That keeps all devils out and away.

Therefore old body have your rest and sleep quiet and in godly peace. You tired eyes close down for that’s God’s good will for now. Close this with in as well: Lord Jesus I am yours! That’s a good and salutary ending of any day. Therefore Lord Jesus, oh Jesus: Good night! (Christian Scriver, 1629-1693)
