答应你的承诺用一生来实现：

I will dedicate my entire life to fulfill my promise to you.
I will dedicate my entire life to fulfilling the promise I made to you.
I will dedicate my whole life to fulfill the promise I made with you.

我觉得承诺的翻译应该是 Promise
注：Dedicate 可以用 Give up 和 use 来代替～

I will dedicate the rest of my life to fulfill the commitment I have made to you.

这个是详细版的。如果是简洁版的：

My life is commited to you.

I'll carry out my promise what I promised you in my life.

Fulfilling my promise throughout my life

一生都履行我的承诺 ！

My life is commited to you.
I'll let my promise come ture with all of my time.
I will carry out the maked promise with all my life.
What I promise to you will be realised with all my life.

I'll use all my life to carry out the promission that I promiss you
