Christmas greetings

Please check and correct the Christmas greetings text I have made to send my partner in the ministry:

Dear Julia,

Sending the warmest Christmas wishes to you and your family.

Wishing you the gift of faith, the blessing of hope and the peace of His love this Christmas and through the new year.
May God shower His choicest* blessings on you and your family.
May the holidays refresh your spirit and bring you new inspiration and happiness.

Thank you for your support, prayer, action and many forms of contact, they have been such a blessing to us. It has been a great joy and honor to join with you in our ministry.

Have a Great Christmas and a glorious New Year!

With love, from
Anya

*Most people would say "best", or an entirely different word to describe it, but in writing "choicest" is fine. Other than that, your English is just fine.
