The promise of eternal life requires that you die. Materially, Christianity offers you absolutely nothing while you're alive. You are, however, pressured into offering time and money to Christianity.
So what does Christianity offer that is immaterial?
Christianity offers hope that things will be better once you die. I don't need Christianity for this. There are many religions that offer the same thing, often with less strings attached.
Christianity offers philosophy. Jesus was a philosopher. However, Christians are compelled to accept as absolute truth everything that Jesus said. Even when Jesus suggested that we don't need to wash our hands before we eat. It has been well established that this is a bad idea. Therefore, it is best to pick and choose from the sayings of Jesus rather than accepting all of them. As an atheist, I pick and choose from religious philosophy all the time. Not only do I not need Christianity to do this, but as a Christian I wouldn't even have the freedom to pick and choose from the sayings of Jesus.
Therefore, Christianity offers nothing materially, and its immaterial offers come at a cost. Christianity restricts your freedoms and wastes your time and money. The little that it does offer can be found elsewhere.
If you don't repent of most of your sins in this life, then your going to have a very bad time in this life before you die, etc...
And that is part of what Christianity teaches, etc...
That is taught both in the here and now and about this life right now, etc...
And if that "fact", and it is or should be a proven "fact" by now, etc; has not become very apparent to very many yet, etc, then people are still very dumb and stupid/ignorant/arrogant, etc...
Might still get into heaven maybe, "maybe", but if you don't ever repent, at least of some of your sins in this life, if not almost all of them during your time here in this life, etc, then your going to have a very, very bad time in this life, before you finally get there, to heaven, etc, if you finally do in the end, etc...
And you certainly will not be called "great" there (in Heaven) if you don't ever either, (repent of most of them here, etc), if you do still get there, or do still wind up there in or by the end, etc...
Oh, and you see it as "taking away from some of your freedoms", etc...?
Well, the only reason I think that you probably think that, is only if, A: you still want to sin and see it as enjoyable but don't realize that it will only bring you a lot of suffering and misery in the end, and in or by the end of "this life" in the end, etc, or B: you look at a lot of "church people" and see how miserable many of them still are, etc, and your judgments are still only just based on that only, etc...
And in the case of "B", then that is only because most church people either still have not repented yet, but are playing the hypocrite, etc, or they have deceived themselves into thinking they have, but have just only become just only more like the Pharisees only in reality, etc, and is why they are all still very miserable still, etc...
Or another possibility is that they are still just exactly still like the rest of the people of the world still yet also, and still have not been separated from all of those sinful desires yet, etc...
But true repentance, of both and/or any or all of these kinds of sins, etc, can only bring real and true joy and happiness ever only, etc, and that is in this life here before you die, etc, and it will carry over into the next also, etc, and in which case, you will be way ahead of others there when you get there, etc, which can be of great advantage, etc...
But bottom line of what true Christianity truly teaches about this life, etc, is that true repentance of as many kinds of sins, or as many kinds of sinful and evil and wicked desires as you can in this life, etc, can only ever bring, immediate and in this life, only true joy and/or happiness in this life while you are here in this life, etc...
And will get you a "little bit ahead" of everybody else in the next life also, etc...
Anyway,
God Bless!
