I suspect that when you talk about "the Holy Ghost testifying to your soul that it is true", you're really just talking about a gut feeling. How would I go about telling whether it's meaningful?
To anybody, who has not been blessed with the Holy Ghost, I can understand how they might think that, but, no, it cannot be mistaken with any kind of human emotion. It is a separate and distinct force that enters the body, engulfing every cell therein, and communicating with it. If our spirits are to be found intertwined with the fabric of our being, which is my belief, it is as though the spirit of God is communicating with another spirit, our spirit, at such a speed that it defies any kind of communication known to man. It is instant and conceptual, filled with an inexplicable rational emotion, but I am not sure how to describe it, other then a pure knowledge and Intellegence, flowing through your body, giving you information, in an instant, that was not before known to you, and I do not mean what the cure to cancer is, but what is our purpose here, why have I lost my job and does my wife truly love me. One thing it is not, for me at least, is a voice in the head, or a whispering in the ear. Such a physical communication would be deemed as archaic once you have experienced the influence of the Holy Ghost. When it leaves you then you know that your body is no longer in communication with it, you get a kind of stupor of thought and that which it wants you to know stands out in your mind like embossed lettering. I once asked the Holy Ghost, in a prayer of fasting, if I should return to university to take a Chemistry degree. The revelation lasted but for a few second, yet took me over a half an hour to verbalise it, even longer to write it down. There can be no mistaking a communication with the Holy Ghost.
Consider your approach in another context: what if I told you that I had a new super-diet: give up all the food you eat and replace them with my special, nutritionally-balanced pills. I guarantee that they'll double your lifespan. I can't give you any studies or objective evidence to back this up, but if you stop eating food and only take my super-diet pills, you'll feel healthier, so you'll know they really will double your life. Are you in?
Oh, I really do not like straw men arguments, as they never quite match the original concept. Like, no such pill would be allowed without stringent testing, there would need to be reems of test results. Sadly, many people would have a go. Those who are familiar with the processes to produce such a pill would not. But I failed to see the argument that you portray. Testing God can produce no nasty physical side affects, however, taking untested pills can.
If you're wrong, and if "living a Christian lifestyle" means a meaningful difference from not being Christian, then you'll have wasted the only life you'll ever have. Every time there was a difference between the "Christian" thing to do and what you would have thought was the right thing to do if you weren't Christian, you would have made the wrong decision. Do you care about the possibility of a lifetime of wrong decisions? I would.
Why do you make a distinction between what a christian would do and what a non-christian would do? Shouldn't they be synonymous. Objective morality exists outside of any and all religions. It is universal and not confined to just religion. We should all be living a moralisticly based lifestyle anyway. What is taught in scriptures is the way in which all of society should live their lives. That they do not necessitates religion to guide and direct us. How can that process be a waste of anybodies time? There will be no Catholics in Heaven, no Born Again's or Mormons. We will all stand or fall on our own choices. If you take a man in the Methodist Church who has lived his life striving to keep the principles of the Gospel, and then take an atheist, who is equally as righteous, would you expect the Methodist to gain entry into the Kingdom of God and the atheist to be locked outside of the pearly gates? I would be interested in your reply, baring in mind, that Christianity is a lifestyle. We do not enter the kingdom of God in congregations, we enter it alone, have attain that level by our own merits. God judges the individuals, one by one, not the congregations for being a Mormon or a Presbyterian.
You seemed puzzled by the fact that people don't see what you're proposing as as good an idea as you do. That's what I'm getting at
Of course I don't. If you were standing in my shoes, in possession of what I possess, wouldn't you be puzzled to?
