But if you read the account in the fourteenth chapter of Mark, it goes a bit deeper than that (no pun intended). Jesus' disciples had taken a boat across the sea of Galilee. Incredibly, they see someone walking across the sea. Peter was apparently unsure that this was in fact Jesus. He was clearly afraid. He said that if it is really Jesus, then he should tell him to step out of the boat and come to him.  Jesus told him to come. Peter stepped out of the boat onto the water.
Peter had good reason to fear. At its deepest depth, the Sea of Galilee is about 150 feet. Imagiine yourself in this situation. The feeling beneath your feet is almost surreal, not exactly like standing on solid ground but more of a mushy feeling, sort of like foam rubber. This feeling is nothing like you have ever felt before. Maybe, you think, I am dreaming.
Thanks to your impulsive exuberance, you find yourself standing in the middle of the Sea of Galilee during a violent storm. You are buffeted by waves and soaked to the skin. Perhaps a lightning bolt flashes, followed by the loud rumble of thunder. Suddenly, the weird feeling of firmament beneath your feet gives way.
Water is up to your knees and you are sinking quickly.The boat is now far behind you. There is no way that you can reach it to save yourself. What have I done, you think, I am going to drown. What a stupid way for it to end.
At that moment, Peter’s faith enabled him to overcome his fear. And for a moment, Peter walked on the water! However, the howling winds and enormity of his situation got the best of Peter. He again was terrified and cried out to Jesus to save him.
And frequently, this is exactly how many Christians respond to fear and worry. Initially, we trust the Lord with the issue. We give the problem to Him. However, when the problem is not solved according to our schedule or plan, we begin to doubt. We allow Satan to whisper his lies to us. Perhaps the Lord didn’t hear my prayer. Or, perhaps He thought my prayer was self-interested and unimportant.
Or perhaps the Lord’s will is for me to suffer.
We are so close to this threatening forest that we cannot see the
Anytime we are faced with a fear that threatens to compromise our faith, we should declare that: “I will not sink.” We should think of Peter, exuberant and faithful, stepping out of the boat towards Jesus. Had he continued to his destination in faith, unwavering and unintimidated, there is no doubt that he would not have begun to sink. We need to develop an intellectual alarm that sounds whenever we begin to feel afraid. As soon as it happens, we remind ourselves that through faith anything is possible, including resolution of the threat at hand.
Once you give a fear or worry to the Lord, don’t take it back. He has heard your prayer. He will deal with the issue, often in ways that we could never have
imagined. Don’t allow Satan to fool you into believing that the issue is not important enough for God, or that God expects you to do something else. Continue to pray and listen for God’s response. Above all else, let it go and quit worrying about it.
I will not sink.
 Matthew 14.
