"我用我的生命发誓这是真的" 英语怎么说?

i swear with my life its true.

its true, i swear with my life.

i bid my life its true.

我用我的生命发誓这是真的
I swear with my life it's quite true
我敢用生命担保
I'll bet my life it is quite true

没有以生命发誓这种说法，不符合西方说话方式～～
可以这么说：
I swear in the name of God that....
I swear to the God that...

I swear with my life that this is true

一般用生命发誓不算是最毒的... 还是向上帝发誓比较猛.. 用作, i swear to God....

I swear with my life!

口语: This is true! I swear with my life!
口语一般没什么从句,越简单的句子越好.
