As I read through the Gospel of Mark, I was struck by the beginning verses and how they seemed to form a "thesis" for the deity and authority of Jesus.
To quote a previous entry of mine:
As it is written in Isaiah the prophet:
"BEHOLD, I SEND MY MESSENGER AHEAD OF YOU, WHO WILL PREPARE YOUR WAY"
[BTW, if you're wondering why it Mark says from the prophet Isaiah, its b/c Mark puts two verses together Malachi 3:1(v2) and than Isaiah 40:3(v3), and as the literary custom of the day, he attributes the entire quote to the higher ranking prophet.]
Now that we see that Jesus from the outset is equated with YHWH God, let's see how Mark develops His Authority in his Gospel:
Mark 1:1, 1:11, 9:6 - Authority as the Son of God (Not only does Mark, but God the Father explicitly calls Him "the Son" ~ Talk about a letter of recommendation!)
Mark 1:2-3 - Proclaimed as the predicted Lord and YHWH Himself
Mark 1:27 - Authority in Himself
Mark 1:29-34 - Authority over disease
Mark 2:5-7 - Authority to forgive sins
Mark 2:10, 14:62 - Authority as the Son of Man
Mark 2:28, 3:11-12 - Authority over the Sabbath
Mark 4:41 - Authority over the creation/natural world
Mark 5:41 - Authority over death
Mark 6:48 - Authority over the laws of nature
Mark 6:41 - Authority over matter and the power of creation ex nihilo (ie to create something out of nothing)
Mark 8:29 - Authority as the Messiah/Christ
Mark 9:2-3 - Authority of the Kingdom of God and power/The Transfiguration
Mark 13:26 - Authority to close the End of the Age
Mark 13:31 - Authority and eternity of His Words
Mark 14:22-24 - Authority of the New Covenant (to initiate it and that His blood is the New Covenant)
Mark 14:22-24 - Authority to institute new sacraments for God's people
Mark 15:39 - Authority of His Death
Mark 16:6 - Authority of His Resurrection
This is by means no means an exhaustive list of verses, but definitely gives a good bird's eye view of Christ's authority and really His equality with God/YHWH. As best put by the Pharisees in Mark 2:7 "Who can forgive sins, but God alone?" They were right about, but failed to realize Jesus was God.
Praise be to our Lord, God, and Savior Jesus Christ!
