This time of testing was a challenge to the disciples" faith in Jesus" word (cf. Luke 8:13). They stopped believing momentarily. Their double address, "Master, Master," showed their urgency. Jesus reminded them of their unbelief with His question. Luke recorded a milder rebuke than Mark did ( Mark 4:40) perhaps showing that faith is a dynamic quality that grows and shrinks (cf. Luke 8:13-15). The disciples" question showed their lack of perception of Jesus" true identity (cf. Luke 9:20). They had believed that He was the Messiah, but they had thought of Him as their contemporaries did. Now they saw that He could perform works that only God could do (cf. Psalm 107:28-30). The disciples should have trusted in Jesus" word. [source][source][source]
"Assuredly, no narrative could be more consistent with the fundamental assumption that He is the God-Man." [1][source]
Christians have often seen this storm as typical of the storms of life we encounter that threaten our faith (cf. James 1:6). [source][source][source]
"The point of connection is not in the precise situation the disciples face in the boat, but in the feelings of helplessness they have about where Jesus has led them. Events in our lives sometimes leave us feeling at risk, whether it be in a job situation that calls us to take a stand, in the severe illness of a loved one, in an unexpected tragedy, or in the breakdown of a relationship. Any of these can be a storm in which we doubt God"s goodness. We may feel God has left us to fend for ourselves." [2][source]
Experiencing deliverance in such situations should expand our appreciation for Jesus. [source][source][source]
