Extremely Rare: When the Orthodox Get It Right on Grace and Predestination

In this case, an Orthodox saint, John Veniaminov (St. Innocent of Alaska):

Brethren, you have heard that the goal of our Society is to advance the conversion of those who do not yet believe in Christ our Savior. That is, we accept, each according to his abilities and the measure of his zeal, to further the conversion to the Orthodox Faith and the Truth of those among our fellow countrymen who still wander in the darkness of unbelief. As you can see, the work we hope to advance is great and holy and truly apostolic.

In order to obtain the success one desires, even in ordinary tasks and undertakings, it is necessary to muster (independently of financial means) intelligence, knowledge, experience, ability, activity and energy. When with all of this the circumstances are just right, one has reason to hope for success.

Now, in the work we wish to advance, this does not in the main apply. To be sure, we too will need (in addition to financial means) intelligence, knowledge, experience, ability and so on, but we cannot - and must not, even under the best of circumstances - count on these factors as a sure means of attaining our goal. And why not? Because man's conversion to the path of faith and truth depends entirely upon God. "No one can come to me", said the Savior, "unless the Father who sent Me draws him to Me" [Jn 6:44]. Therefore if, according to his inscrutable judgments, the Lord does not wish for a given person or nation to be converted to Jesus Christ, even the most capable, most gifted, most zealous of workers will not succeed in his task. (Address of Metropolitan Innocent Veniaminov to the Organizational Meeting of the Orthodox Missionary Society, 1868. Quoted in Alaskan Missionary Spirituality, ed. Michael Oleksa, p. 141)
