You start with 2 Options, with 2 Choices...

1) Christianity is a big lie, a big scam, a big superstition.

2) Christianity is the True Faith which leads people to Heaven.

If you insist Option 1 is correct, well, follow along anyway with the logic below.

Suppose Christianity is the True Faith, as we Christians insist.

The most conspicuous problem with Christianity, if Christianity is true, is that the same scriptures which tell us Christianity is the True Faith also tell us there is only one True Church.

But Christians have divided and subdivided Christianity into thousands of separate denominations / thousands of separate churches.

If it is insanity to think that every church you stumble across is none other than God's True Church, the Church which Christ founded on a rock, the Church we read about in Matthew 16.13-19, if lots of Christian denominations are false churches - if they are lost in heresy and so they lead people to perdition and not to Heaven...

How are you going to make sure that you find a Church which will lead you to Heaven?

How do you make sure you don't get ensnared by a false church which is lost in heresy, one which will drag you down to eternal perdition?

Well if Christianity is the True Faith, then the trustworthy scriptures tell us...

2 Thess 2 tells us that the Antichrist will show up prior to the Second Coming of Christ.  And the False Prophet is also on the schedule to show up.

Revelation 14. 6-11 tells us that 3 angels from Heaven will show up sooner or later.

Suppose an angel shows up.  How do you determine if that angel is an angel from Heaven or an angel from Hell?

Suppose an angel shows up and says the Russian Orthodox Church leads people to Heaven. If that angel is speaking the truth, if he is leading people to Heaven by pushing the Russian Orthodox Church, then he must be an angel from Heaven, assuming he never falls into heresy.

But if he is telling a lie...if in fact the Russian Orthodox Church is a false church lost in heresy which drags people down to eternal perdition, then, since that angel is leading people to perdition with his lie, he must be an angel from Hell, assuming he never repents.

Or suppose an angel shows up and announces that some obscure little sect, and only that obscure little sect leads people to Heaven. Suppose he says every other Christian denomination is a false church lost in heresy which leads people to perdition.

Well if he is speaking the truth and is leading people to Heaven then he looks to be an angel from Heaven, provided he doesn't start telling lies.

But if he is telling lies and is leading people to perdition with his lies, then he must be an angel from Hell, assuming he never repents.

So, unless you already know how to identify God's True Church with 100% accuracy, you might not be able to determine, should an angel show up, if that angel is an angel from Heaven or an angel from Hell.

As I mentioned in my Smashwords / Draft2Digital bio, my books have become like rough drafts.

I've moved things over to You Tube where I have tried to refine my arguments, have tried to make them mass-market material.
