What is the most expensive religion?

Probably some marginal sect which requires clothing of gold and selling a kidney to manage the required sacrifices...

Seriously, I think it would be presumptuous of me to voice an opinion because I am not familiar with all the religions out there. I do, however, believe that most religions (at least the bigger ones) allow both the "dollar per day" and the "million dollars per day" kind of worship... Christianity certainly does :-)   

The one that denies you the truth and the way to real salvation.

To me the most expensive religion is any religion that does not believe in Jesus, Christ the Son of God.  Because non belief in the Son of Man, Jesus will not get you into Heaven and you will not have eternal life. 

I would suggest the the most "expensive" religion/path is one that is not able to give the 'individual' soul the DIRECT Transcendent 'Experience' of its own Christ or Perfect Consciousness.  Ones that have heaven only as their goal and cannot deliver the actual Grace which is necessary to awaken one's own dormant INNER Divine Energy  ... which reveals the Divine ONE within.    No religion owns Grace or The Grace Bestower.

The most expensive religion has no provision for sin and no savior the one that gives you salvation by your own works thereby condeming you to eternal hell. For by the law no flesh shall be justified. We are justified soley on the finished work of jesus christ alone. Not of works lest any man should boast. 

Jesus christ is the only name under heaven by which man must and needs to be saved.

God give me the patience to speak gently.

There is a clear and unmistakable difference between Christianity and every other religion that ever existed: what we believe is real!

"That which is born of flesh is flesh.  That which is born of spirit is spirit."  The difference is utterly simple and utterly undeniable: Christians really are born again!  No one else can say that.  No one.

What happens when a person is 1/3 dead?  Will you awaken that dead third with magic incantations or readings from the Vedas? 

Try all your life and you will find that you have memorized all those lines and still, that third of you that you were supposed to bring alive, is still dead.

Christians are unique in that we asked God to bring that dead third of us alive!  He did!  We can attest to that fact each from a powerful and unmistakable event that changed our very essence, and left no question whatsoever! 

Religion is memorizing words, but faith is to bring that which was dead, alive!

Never underestimate the power of a living spirit!  Your enlivened spirit really does connect to infinity!  It is as real as infinity and just as powerful.

All living things have a will of their own -- that is how you know it is truly alive!  The born-again experience will bring that part of you which was dead, alive, and there is just no way to contain a connection to infinity!

So, you could call the Christian life the most expensive religion that ever was, because it really will take everything you are and change you around -- to someone who is infinitely better and stronger than you could have imagined before.  All of a sudden, you realize that all your wealth means nothing, no matter how much you have or how little.

You cease to be the owner.  You become the steward.  And then, you will be amazed how much you are willing to give, not for a tax write off, but from an awakened human spirit.  You don't just look at the other guy's misery or joy -- you feel it.  You don't just look at the beggar with a cardboard sign and automatically hand him everything in your wallet -- you feel something about him, that he is trying to make an indecent profit from falsely claiming that he is in need.

You may never be able to explain it, but when you come awake spiritually, you don't need to.  It changes you.  It makes you genuinely whole.

Aahhh  one can only hope that you are not equating sacred non-dual Vedantic Mantras with dualistic magic incantations here... since these sacred mantras come directly from the mind of God .. while the later are nothing but creations of the finite mind of man. 

  Clearly you have had some sort of Divine Experience.. however my sense is you have stopped WAY too soon. Might I suggest that a little knowledge can be a very dangerous thing.. especially when the source of that knowledge is processed through the dualistic mind... which is veiled by the impure ego, which yours obviously is.  No one who has ever merged into The Infinite Christ mind would ever make the claims You do... so please consider that there is a lot more to the ONE Christ than your finite mind is currently aware of.  And also that Grace has even more knowledge to bestow on you.. you WILL be amazed.. and incredibly humbled.  Peace.
