The sole purpose of Orthodox Christianity is the salvation of every human person, uniting him to Christ in the Church, transforming him in holiness, and imparting eternal life. This is the Gospel, the good news, that Jesus is the Messiah, that he rose from the dead, and that we may be saved as a result.
