What Am I

At night I shine upon my face A gift I am when in the dark I'm sent to you by heavens grace No match is needed for my spark. A gift I am when in the dark But when it's day I never show No match is need for my spark At night I give a gentle glow. But when it's day I never show No secret though am I to see At night I give a gentle glow Now can you guess the name of me? No secret though am I to see I'm sent to you by heavens grace Now can you guess the name of me? At night I shine upon your face.
