You ask me why I know His blood can cleanse alone;
You ask me why I know He sits upon the throne,
And why I know He chose me for His own;
It's in my heart, it's in my heart.
It's in my heart this melody of love divine;
It's in my heart since I am His and He is mine.
It's in my heart, how can I help but sing and shine
It's in my heart, it's in my heart.
