Why was Jesus afraid/agonizing in the Garden of Gethsemane if the Spirit of God isn't one of fear but of power?

The scene of Jesus praying in the Garden of Gethsemane has confused me for a time. How could Jesus be overcome with fear or anguish or what-have-you when his Spirit is one of power and self-control, not of fear? > **Luke 22:42-44 ESV** “Father, if you are willing, take this cup from me; yet not my will, but yours be done.” An angel from heaven appeared to him and strengthened him. And being in anguish, he prayed more earnestly, and his sweat was like drops of blood falling to the ground. > > **2 Timothy 1:7 ESV** for God gave us a spirit not of fear but of power and love and self-control. Could it be that Jesus was not actually afraid, but anguish means something else? Other translations, actually most, say he was in agony or "in agony of spirit". What is an overview of doctrinal opinions on this?
