If I study the bible and develop my own doctrines wouldn't they be "man made" (by me)?
If you've developed your own interpretation of the Bible isn't that interpretation"man made' (by you)?
OB
There is no own interpretations . Just read what it says . There are so many denominations because people make up doctrines that are not here.
I see what you really asking , why Christianity and not Islam or Hindu ? If there is God why is he in this and not the other . It's simple , in every religion in this world you have to pay.
In Hinduism - you have to pay offering and pray
In Islam -you have to pay ,pray and be obedient
In Buddhism - you try to not want anything so you don't have to pay , but untill then you pay with meditiation
In Judaism - you have to pay by keeping law , sacrifices and obedience with prayer
In Catholicism- you have to pay with sacraments , mass , obedience to law and doctrines of Catholic Church
Paganism - you have to do offering , sometimes human offerings to please gods
Christian Baptism - most of them you have to pay by baptism
Christian Presbyteranism - you pay by speaking in tongues
In every religion you have to pay , and every Christian denomination have something to make you pay.
Only in Biblical Christianity you don't have to pay for anything because Jesus paid in full for you on cross with his blood.
That's why it's distinct from other religions/denominations.
Moreover i would never believe in any word of Bible if it was not proven , i don't believe in Qu'ran or in Mormon's , because they don't have any proof that God write them.
Only Bible has proof of prophecy that this is from God , he is using his atribute - that he is outside of time so you know that it's from him. Here is list of fullfilled prophecy (Bible is about 30% prophecy ).You will not find any prophecy in any religion apart from Biblical Christianity.
AccordingtotheScriptures.org :: 353 Prophecies Fulfilled in Jesus Christ
If you are scientist you can estimate using math the probability of somebody fullfilling them , even if you don't believe some of them are 700-2000 years before Christ , all of them were translated from Hebrew to Greek in LXX before Christ came to fullfill them so there is no excuse .
If you don't know probability this guy did it for you.
There are 3 options really :
a) Christ is Lord , you call him and do what he says
b) Christ is Lier , you know that God exist but say that he is not Christ so you move on to other religions
c) Christ is Lunatic , you stop wasting your time on religion and move on
But since you are seeking God by attempting this forum then there is something inside of you which drag you here , you want to choose option B because you still want to have charge over your own life instead of being Atheist , but you want to douse that burn inside of you by attending church and being religious .
God said be Hot or Cold , so you either believe in him and do what he says or you don't and stay atheist , you choose lukewarm to not feel guilty but it will profit you nothing.
Love you
