Man tends to ignore God's justification. Opus Dei should be the mission of all believers, but especially the leaders in churches. The purpose of this article is to answer several questions including: What does justification mean in the Bible? What are the characteristics of leadership? How is Opus Dei in the world: A Doctrine of Justification Educational Challenge for Recipients of the Relay of Church Leadership? A literature study informed this work that demonstrated that: (1) Justification belongs to God and is given to man. God removes guilt and punishment for his sins. (2) The factors that influence the success of leadership are: being an effective leader, implementing Christian leadership, everyone being a leader, and deciding God-centered policies.
