Summer snow. By Keith Green.

"Unexpectedly, you came back to see, If I was waiting, like I promised long before. Your shadow filled the room, the music changed it's tune, When I saw you, you were standing at the door.
Like summer snow, you were an unexpected sight. A blazing sun, you were shining in the night, When I really should have known, that you'd be coming home.
I waited patiently, but I found it hard to see, If you were coming, why was there such a long delay.
At times I thought you lied, or else you would have tried, To let me know that you were coming back today.
Like summer snow, it falls around me in the cold. I can hear the echoes, of the warnings I was told. That I should know, that you'd be coming home. Like summer snow, you were an unexpected sight. A blazing sun, you came shining in the night, When I really should have known, that you'd be coming home. Unexpectedly, you came back to see.."
