The sea became rough because a strong wind was blowing. When they had rowed about three or four miles, they saw Jesus walking on the sea and coming near the boat, and they were terrified. But He said to them, "It is I; do not be afraid." (John 6:16-21)
Fear is sometimes good for you. It stops you from taking unnecessary risks. From
being reckless and unthoughtful in what you do. Fear is natural.
It is a human emotion like all the others. Fear can be real and warranted - we fear punishment and retribution for our crimes, we fear threats from aggressive people, we fear criminals, wild animals and so on.
Or fear can be imagined and unwarranted - we fear the unknown, new places we have to visit, new situations in our lives, new people we have to meet, or we fear change from the comfort we're used to, we fear what might happen in the future.
So fear, by itself, being natural, is not a sin. But how we react and deal with it can be. Too much unwarranted fear could be an insult to God in that we do not trust Him enough to look after us and care for us. Prayers are the answer.
Let us consider carefully what it is that causes our fear and if there is a genuine reason then we should seek help. Discuss the matter with a trusted relative or friend. If there is cause for concern then we should not suffer and worry alone. Others may be able to help us or get us to see our problem from their perspective.
If however our anxiety is without foundation; and there is nothing practicable we can do to change the situation; we should trust in God. This is what He asks of us. To tell Him how we feel and seek His help to calm us down. He has conquered fear. He has conquered the future. As well as evil. Forever.
Do not be afraid – I will save you. I have called you by name – you are mine. Isaiah 43:1
It is no point having faith in a Master who walks on
water if we do not trust Him enough to follow Him.
