Should I write 'god' with a small 'g' or a capital?

god里面的字母g，我该写成小写还是大写？

《牛津词典》

So that will be appearing in your text as "God" with a capital G.

所以在你们书上，上帝的首字母是大写的。

Okay, God. We have the word "God" being used I guess in that translation, right, with a capital G. What else is used?

没错，是上帝，我们在那张纸上，有关于上帝一词的翻译,大写字母G打头的，还有什么其他说法？
