3.4.7 The ministries of Christ–King, Priest, and Prophet
The title "King" is associated with the notion of reigning and ruling. Priests performed sacrificial services in order to effect reconciliation between man and God. Prophets were expected to proclaim the divine will and foretell coming events.
Ruling and reigning, effecting reconciliation with God, proclaiming God's will and foretelling future events–all of these can be found in perfect fashion in Jesus Christ.
