Idea for wedding vow

When fate knocks at your door, know that I will drive it away, and be aware that even when death comes to claim you, I will stand in its way. Should everything around you die, do not forget: I will live for you for your path is my path, and at its end awaits our triumph. Misfortune shall be as nothing when we stand together and our love eternal.
This is the proclamation of Two Lives As One.

How does it sound?
