Exodus 3:2
"And the angel of the LORD appeared to him in a flame of fire out of the midst of a bush. He looked, and behold, the bush was burning, yet it was not consumed." 

In Exodus 3:2, an "angel of the LORD" appears to Moses.  Notice in the following conversation both God and the LORD are referred to as speaking to Moses.  The "angel" is not mentioned again.  

God deploys His angels to carry out His purpose from the beginning (Genesis 3:24) to the end (Revelation 22:16) of Scripture.  Sometimes the angel is referred to as the "angel of the LORD" as in this passage.  The first usage of the angel of the LORD is in Genesis 16:7-13. 
Scripture identifies the One speaking with Hagar as "the angel of the LORD" until verse 13 where Hagar "called the name of the LORD who spoke to her, 'You are a God of seeing.'"  Therefore, it was not merely an angel speaking to Hagar; it was God Himself speaking to her.  We see the same thing in this passage where God speaks to Moses.

Many theologians identify this "angel of the LORD" as the pre-incarnate Son of God.  Notice in Exodus 3:14, God names Himself "I AM," the name Jesus uses seven times to refer to Himself in the Gospel of John.  

Another interesting example of the pre-incarnate Son of God appearing is in Joshua 5:13-15.  Notice the "man" allows Joshua to worship Him without correcting him.

Luke 6:27-31
What astonishing commands: Love your enemies, do good to those who hate you, bless those who curse you, pray for those who abuse you, to the one who strikes you on the cheek, offer the other, give to everyone who begs from you.  Each of those phrases is a command from Jesus.

When I honestly examine these commands and my ability to obey them, I realize for me to live this life is impossible.  It is only possible through the supernatural life of Jesus living in me.  This life requires me to no longer live for Roy.  If my life is about me, none of these responses is possible, yet, if Christ is living through me, it is He (Christ) who responds.  So, anytime I react differently, am I living for me?  

Job 20:29 
"This is the wicked man’s portion from God, the heritage decreed for him by God.” 

Zophar picks up where Bildad left off in Job 18 describing the life of the wicked and godless.  Zophar describes their short life as empty, joyless and never satisfied because even in prosperity there is no peace, joy or contentment.  After this dark portrayal of the wicked's life, Zophar says, "This is the wicked man's portion from God, the heritage decreed for him by God." (Job 20:29)  What a dark and dismal picture both Bildad and Zophar paint of the life of the wicked.  To be told this is the wicked's portion and heritage should cause one to stop and think.

Would you not rather have the portion and heritage promised in Psalm 16?  David says the LORD is his chosen portion and he has a beautiful inheritance.  He concludes this passage with the promise of the fullness of joy and pleasures forevermore. 

LORD, You make known to me the path of life.  There is no good apart from You.  Because of You my heart is glad, my whole being rejoices, and I shall not be shaken.
