You can find the definition of the Christian God in the New Testament in John 1,1. But you have to go into the Greek original language to understand it, since all translation beginning with the first on into Latin (Vulgata) are absolute trash. In the original Greek God is defined as “ho logos”. If you want to understand what this is about, you have to read how Heraklit understood ho logos.(the Greek ho logos has many translations, and of course the stupid translators picked the worst one (“the word”) which does not make any sense at all). Heraklit’s understanding of ho logos is very scientific, and I can agree to what Heraklit wrote about ho logos (I am a scientist) and therefore can say “I believe in Ho logos = God (this is a bijection in John 1,1). You should read that definition by Heraklit (you can find it in the Internet), it is vey interesting! The problem with Christianity: the stupid “followers” of Yeshua defined God according to all the idiotic translations in other languages (it’s always the same: the brainless followers ruin everything, today as much as they have have been doing this for millenia). So people are fighting about a word which has nothing to do,with the original meaning - that is real stupidity……
