Speartip.

Open the key to the closed door,
Where you went and had gone before,
To unlock the good deeds you had done,
What will make you remembered by anyone.

Do these actions everyday,
And repeat until you are clean,
This is the good person's life,
The one devoid of sin.

We are barely human,
It is our nature to sin,
The devil shall win,
And we shall cry.
