I have been looking for a song - the lyrics begin like this:

I heard about how Jesus turned the water into wine
How He walked along the sea of Galilee
How He rose one Sunday morning just to save us from our sins
And I'm so happy just to know that I am free
Do you believe? Yes, I believe that Jesus watches over me
Do you have faith in God? Yes, I do
And are you sure that Jesus loved you so He died on Calvary
Yes, I'm sure, I have faith and I believe.
