 God enters the picture
   How?

Read Exodus chapters 3 and 4
Special attention to 3:1-6

 

 

  Moses' Calling  was it a

 A. Command   B. Request   C. Opportunity  ?

.       .       .       .
.
1.  God got Moses attention.          a bush in flames but not burning up something impossible as far as Moses was concerned        Exodus 3:2-4
2.  God spoke.                             Moses had no doubt that it was God speaking because of  #1.                                            Exodus 3:4
3.  God said.  "Moses Moses"       repetition I believe places great emphasis or importance to the meeting.     reference Revelations 18:2  "And he cried mightily with a strong voice,
                                                                                                                                                                                                                                         saying, Babylon the great is fallen, is fallen 
                                                                                                                                                                                                                                         and is become the habitation of devils, and
                                                                                                                                                                                                                                         the hold of every foul spirit..."
4.  Moses said.    "Here am I"       states his availability                                                                      reference Isaiah 6:8    "Also I heard the voice of the Lord, saying, Whom
                                                                                                                                                                                                                               shall I send, and who will go for us? Then said I,
                                                                                                                                                                                                                               HERE AM I; send me" Isaiah
5.  God said.  "Put off thy shoes"  emphasis on respect even as far as the ground surrounding God                                         Exodus 3:5
6.  God said   "I am the God of thy father, the God of Abraham, the God of Isaac, and the God of Jacob."   identification                  Exodus  3:6
     Moses hid face.
     Moses was afraid to look upon God.    Why?  
.       .       .       .

             A.  He was showing respect    B.  He was frightened    C. He was unworthy
