Lyrics:

I believe in the sun even when it is not shining
I believe in love even when feeling it not
I believe in God even when He is silent
Hear my prayer

I believe in the sun even when it is not shining
I believe in love even when feeling it not
I believe in God even when He is silent

Hear my prayer
Hear my prayer
I believe
I believe
Hear my prayer
Hear my prayer
I believe
I believe
