Christ is God's provision for eternal life - the Bread of life who feeds hungry hearts. The disciples in the boat were alone in the dark while Christ was on the mountain. It is in dark times that we feel afraid, when we feel apart from Christ, but Jesus came to them, walking on the water, in their time of weakness, after the tempest had begun on the sea. We are reminded that Jesus waits for weakness in order to build faith that waits on Him. It is often not until we come to the end of our strength that we look to His strength. The disciples were afraid because they didn't recognise Christ's nature - 'It is I...do not be afraid' was Christ disclosing Himself as the Creator, 'I am who I am', the Ruler of the waves. Jesus' presence is the power, showing His vigilance for His people. Nothing can separate us as believers from the love of God. Because of His presence, we do not need to be fearful. He will hold us fast.
