And incidentally, the fact that the original manages to harness the tune of the very pagan “To Anacreon In Heaven” — and give it a sober kick-ass power that it never had as a drinking song — is a testimony to the conquering Christ. Christ does not stand on worldly ceremony and is not daunted at all from His resolute mission by small minded people’s hoots at Him (though He is grieved). He owns the entire world. He paid for it. We (as Christians) are in a mop up operation now, clearing out the devils as God sets up the battles which also train us. Those who all their lives stubbornly refuse to join the spiritual revolution, the revolt against Satan, will go to where their captors will also go, which is to infernal regions.
I’ve read and re-read your post to ensure I’m understanding your point and I think you need to read to the end of The Book where Christians gain Heaven while this world passes away with its various demons and Satan. Christians have no battle for this world (i.e. no “mop-up operation”) but do have a battle to claim souls for the Kingdom. The world has already stands condemned, the only hope is for those called out of it by Christ who owns the Church as His Body.
You’ve attached way more import to both the National Anthem and my post than even I could. It’s OK to disagree on a performance or performer without making it a test of faith and salvation.
