Welcome! Here is some rap for you

Lookin’ out at the world through my window pane,
Every day has many colors ‘cause the glass is stained.
Everything has changed but remains the same,
So once again the mirror raised.
And I see myself as clear as day,
And I am goin’ to the limits of my ultimate destiny,
Feeling as though somebody somewhere is testin’ me.
He who sees the end from the beginning of time
Looking forward through all the ages:
Is, was, and always shall be.
