Matthew 14:22-33; Walking on the Sea

When the Apostles first saw Christ walking towards them walking on the water they were afraid, in Matthew 14:26 it says, "they were troubled, saying, It is a spirit; and they cried out for fear." I thought this was interesting, because I would think that they would recognize their leader. Then Christ told them who He was and Peter had an incredible response, I love what he said to Christ, in verse 28 he said, "Lord, if it be thou, bid me come unto thee on the water." To me this indicates that Peter had incredible faith in Christ, the feat of walking on water is impossible but he know that His Savior could help him to be able to do it.
But in verse 30 Peter began to sink because he saw the wind and he was afraid. In his moment of fear he began to sink because fear is the opposite of faith. When he began to sink he cried out "Lord, save me." I love what it says in verse 30, "And immediately Jesus stretched forth his hand, and caught him" I really like the immediacy that Christ had in saving Peter. It shows me that when I ask Christ will be right there to help me.
Doctrine and Covenants 88:67 talks about how there will be no darkness in the bodies and that they will be filled with light. I think that this can be connected to the story of Christ and Peter walking on water, because if we are filling our souls with light then there can be no darkness. I think that this connects with fear and faith, because if we are filled with faith then there can be no room for fear in our lives. I love that idea, that if I make sure my life is full of faith then I won't need to fear about things because I have that trust in my Savior and my Heavenly Father, just like how when Peter was full of faith he was bale to walk on the water.
