我坚定的相信英文

这一般都需要用从句的形式来表达，开头这么说ifirmlybelievesthat，that后面就跟你坚信的内容。

I believe / am sure (that) I will keep it on / persist in it / persevere in it / uphold it / insist on it / stick to it / adhere to it / cling to it / stick at it / stick it / stick with it / be insistent on it.我相信我坚持。

I firmly believe.

I strongly believe + that 从句 或者是 + something我觉得最恰当faith 有命运的意思例如 I have faith in you. 我相信你能做到。一般我用faith的时候多数接人而不是物。I have faith in + someone但也许是个人习惯。

I firmly believed that... I was convinced that...

I firmly believe应该系甘

I do believe!

I have faith (in something).faith就是很坚定的信念。
