I'm sure you've heard this but it is a good reminder: anything that comes into your life had to be okayed by the Father. He is totally in charge. Nothing gets by Him. Nothing. So, if you are dealing with a difficulty than there is some good in it for you. Everything God does is good though sometimes it might not be apparent at the time.
The disciples are in the boat. The sea is raging. They are so scared. They are sure they are going to drown. Jesus walks toward them. This makes them even more frightened for they fear it is a ghost. Jesus doesn't condemn their fear. He assures them of His presence. He says to them, "It is I; do not be afraid."
There are times when we fear, when we are overwhelmed in this life. During these times we should hear Jesus saying the the same thing to us, "It is I; do not be afraid."
He is there right with you. He is not going to leave you alone ever. Hold onto Him. And keep holding onto Him until you see the answer to that prayer.
