Richard,
While I was attempting to translate the Prayer into English, it was brought to my attention that a more worthy translation existed. This translation far better reflects the spiritual tenor of the words expressed by Nikolai, than I could ever hope to attempt.
The Coronation Prayer has been provided by the Russian Orthodox Church in Dallas Tx, with thanks.

"O Lord God of our fathers, and King of kings,
Who created all things by Thy word, and by Thy wisdom has made man,
that he should walk uprightly and rule righteously over Thy world;
Thou has chosen me as Tsar and judge over Thy people.
I acknowledge Thine unsearchable purpose towards me, and bow in thankfulness before Thy Majesty.
Do Thou, my Lord and Governor, fit me for the work to which Thou hast sent me;
teach me and guide me in this great service.
May there be with me the wisdom which belongs to Thy throne;
send it from Thy Holy Heaven, that I may know what is well-pleasing in Thy sight, and what is right according to Thy commandment.
May my heart be in Thine hand, to accomplish all that is to the profit of the people committed to my charge,
and to Thy glory, that so in the day of Thy Judgement I may give Thee account of my stewardship without blame;
through the grace and mercy of Thy Son, Who was once crucified for us,
to Whom be all honour and glory with Thee and the Holy Spirit, the Giver of Life, unto the ages of ages.
Amen."
Declared by Emperor Nikolai Aleksandrovich
