God and Christ are used synonymously because Christ is part of the triune God; The Father, The Son and The Holy Spirit. God consists of these three personalities. You can search the internet for the Trinity to learn more about this unique characteristic of God. The answer to your second question on why I became a Christian instead of a follower of any other religon, is simple. As a Christian I believe in the salvation system of
Calvinism, a doctrine that teaches that people are saved through the grace of God by an unconditional election. While this doctrine of salvation may not explain to you the reason for my personal conversion, it can throw some light on the matter. My personal testimony would be that one day some time ago, I for some reason came across some articles arguing for the existence of God. I was not very convinced at first, but gradually I started to realise that I had been a fool for many years; a fool to deny the existence of God. I prayed to God and said that if he really was out there, convince me that He is, and thereafter lead me to the right conclusions about Him. Unaware of the great act I had done by placing my faith in God, the
perseverance of the Saints was starting working within me, and after that I have found it impossible to deny God; both because of the logical reasons why He exists and the personal experiences with Him and the great changes that have taken place in my life (I was the typical a-hole atheist before I was saved, but no longer). I mention that I prayed to God and asked Him to lead to me to right conclusions about Him, and He lead me to the Christian faith. The overwhelming evidence for the truth of this religion I just could not ignore and an inner convincing feeling made me place my trust in this religion as the right one. (Although there are many Christian churches and doctrines that are wrong.) Being a Christian feels so right, and then it probably is.
And no, I'm not in a Christian community, I don't go to church, and I'm not baptised either. My faith is a personal one.
Indeed it has been forced on many to attend church and be baptised (by water), but one can
never force anyone to truly believe in something. They can lie about it and call themselves Christians, but this does not mean that they are baptised by the spirit and truly knows God and will go to Heaven. Not all 'Christians' will go to heaven.
Again, some Chinese people may call themselves Christian and not be so, but why would they? The only thing they have coming by doing so is persecution by the Chinese government. The only thing that matters is the personal faith and relationship with God, accepting His Son Jesus Christ as Savior. I strongly doubt that most Christian missionaries convert people by offering them riches. A true believer in Christ will not be influenced by these earthly items; a missionary that truly believes in Christ will not offer money to the chinese for convertion, and a true chinese believer will not accept the money and convert because of it.
I could go on and on answering your questions and statements, but rather I will suggest the amazing Christian website
www.gotquestions.org. This site can and
will answer all your questions on Christianity. But in the end it is up to you if you accept the religion or not.
