Before going to bed last night, I know you were probably thinking about the Trinitarian affirmation of Jesus in Mark 1 followed by his temptation in the wilderness. Like you, I have been meditating on this passage for the last four days. Here is a brief thought:
a) The Trinitarian formulation in Mark 1:9-11 serves as an affirmation of the blamelessness of Jesus. As the Father says to the Son: “You are my beloved Son, with you I am well pleased.” In Job 1, God the Father affirms Job as blameless: “…there is none like him on the earth, a blameless and upright man, who fears God and turns away from evil?”
b) After Jesus is affirmed in Mark 1:11, Mark says that He was immediately sent to the wilderness to be tempted by Satan. After Job is affirmed by God, he is also sent to be tempted by Satan.
c) Thus, Christ is the greater Job.
