Can you tell me who sings this song and where I can get digital or sheet music?

i was wanting to know who sings this song. i heard this song alot of times on the radio.

BE NOT AFRAID

Rocked by waves and howling winds
And the storm that threatened them
The disciples sailed a boat on Galilee
They were tired and full of fright
They had fought the storm all night
Then the master came walking on the sea

(Chorus)
Be not afraid for it is I, in the fourth watch of the night
You fought and prayed, but I am here and it's alright
The storm will rage, the winds will blow
But they are under my control
It won't be long 'til morning breaks
Be not afraid

Hope seems gone, the day is done
And the night keeps pressing on
Doctors say that they've done all that they can do
Around the clock the family prays
But help's already on the way
Without a doubt, another doctor's in the room

(Chorus) x 2

The storm will rage, the winds will blow
But they are under my control
It won't be long 'til morning breaks
Be not afraid
