Orthodox believe in the synergy of God's grace and human response. The human response is manifested both through faith and through good works which reach their perfection in love.
The prime example of synergy is the Theotokos (Virgin Mary) who was chosen by God's grace ("hail, full of grace") yet who responded to that grace by her free will ("be it done to me accoring to Thy word").
Even Martin Luther thought that trying to separate faith and good works was to create a false dichotomy. "One can no more separate good works from faith than to separate heat and light from fire" (paraphrase of Luther's preface to his commentary on Romans).
