Please correct my written English vow for my fiance in our upcoming wedding.

You are God’s precious gift to me, my springtime, my hope and my joy.
You are everything that is pure and true. And I adore you with my mind, body and soul.
How blessed I am to be able to say that you are mine, to be able to love and cherish you for the rest of my days.

I vow to always be there, to comfort you in your sadness, and rejoice with you in your victories.
I promise to love you all my life with all my heart.
I pledge to be there when you need me, to fill your days with sunshine, to comfort and encourage you, to be your never-ending best friend, and to love you all my life, with all my heart, for so long as we both shall live.
I will trust and honor you, I will laugh and cry with you.

I will love you faithfully, through the best and the worst, through the difficult and the simple.
I can’t guarantee that there will be no problems but I can assure you, that we are going to face them together.
There’s no way that we won’t argue in some occasions but I believe those can help us grow together.
What may come I will always be there. As I have given you my hand to hold, so I give you my life to keep.

I really thank God for having you.
I also thank you for giving me this wonderful opportunity to love and to be loved as well.
May our hearts and every breath become one as we unite this day as husband and wife!
I swear to be your true love from this day forward and forevermore as I just want to grow old with you.
God will be the foundation of our marriage.

I love you so much Mylene, my precious wife, my best friend and my lifetime partner.
