I was a Christian for 20+ years, and I served as a youth & adult teacher in various churches for a number of those years. I was also an apologetics teacher for some time. There were many reasons why I left Christianity; one was because I researched & practiced aspects of Buddhist philosophy and psychology to handle various issues, and I found that they worked very well for me. It eventually led me to a full scale acceptance of Buddhism.
Other reasons include: claiming Biblical promises that never manifested, being asked apologetics questions that I had no good answer for (even after much study), etc.
I have not thought about being a Christian again, except I do miss some of its social aspects.
Hi Ananda, I remember reading your post in another thread.
I used to read about Buddhism seriously when I was a youth. The eight-fold path or middle path of Buddhism - which is about right speech, right thoughts, right actions. right meditation etc - is good teaching indeed. However, when I later came to rebirth, I cannot bring myself to believe it, there is just too little proof. Virtually no one can say that they remember their former existence. You will know that rebirth - or trying to stop being reborn so that the wheel of karma will cease, thus leading to nirvana - is the cornerstone of Buddhism. Many people are Buddhists in Singapore (where I reside), I have friends who practise Buddhism, but none of them remember their past lives.
I have been a Christian for many years now. There is one question that matters when it comes to God, which is: Does He exist, is He real? Whether we feel happy or upset with Him (from time to time), the same question remains: Does He really exist? If He is not real, then as apostle Paul says, "we are the biggest fools.". But if God is real, then we believe and keep faith to the end, no matter how we feel.
Are there sufficient proofs of God's existence? Yes, the creation - - ecology system and the thousands (or possibly million) of land and marine creatures - is solid proof. Can they really have happen and evolve by themselves? Without a Creator God. I really cannot believe they could.
Is there credible proof that the Bible is true? Yes, the Bible spoke of many things that has happened. For example: the ancient Egyptian empire, Israel, Assyria, Babylon, Persia and Roman empire did exist. Archaeology proofs, even recent ones, have supported that the Scripture is credible. The book of Revelation - - written 2000 years ago at a time when soldiers fought with spears and arrows only - - prophesies of tanks and helicopters in modern warfare.
Did Jesus exist? He was recorded in Roman Antiquities, the Roman historian Josephus said He did miracles and many followed him. Is the resurrection real? If not, I don't think the apostles and disciples would have endured so much sufferings and even death.
Personal experience - Answers to prayers and deliverences from serious problems have helped me to keep faith. Of course, there are disappointments too, which bring me to the next point...
Finally about "claiming Biblical promises that never manifested," which is what I mean by "whether we feel happy or upset with Him from time to time": I have known Christians that left God because they are disappointed about prayers not answers, and He does not seem to help when they are in trouble. It is too much to answer in a text and for that, I have written a book "Understanding Prayer, Faith and God's Will" to try to address the questions and problems. I believe that a root problem is how we misinterpreted prayer verses. Understanding what the Bible really says about prayer can help us to perservere and keep faith.
