Okyeame is only a human being. Jesus Christ is true God and true Man.
4.2.2 Functions and entitlement
Okyeame serves only an earthly king. Jesus serves the heavenly King. He serves a divine being. Jesus though he was in a form of God, humbled himself by taking the form of a servant (Phil 2:6-11).
4.2.3 The act of sacrifice and its efficacy
