While I like this song....I heard a preacher preach on it before...He said they didn't have to get scared and cry and wake up the master. They had Jesus on board. All they had to do was have faith and climb in and go right off to sleep with him and they would have been safe.
And as long as we have Jesus on board with us we don't have to be worried and scared we can just have faith and rest in him knowing that he will keep us safe and he knows exactly what we need.
Just felt like sharing that
