We can clean our souls because of Jesus' atonement. To use the atonement we must sacrifice, (cut the top with the staple off). We must sacrifice our pride and be humble, we must sacrifice our sins and give them up, we need to have "a broken heart and a contrite spirit". When we are willing to do this we can use the atonement to wash away our sins and become clean again.
We are baptized to show our willingness to do these things (dump out the tea, open up the tea bag tube and stand it up on the plate).
This is only the beginning, we must do our best to stay clean and continue to repent with the sacrament.
It is sometimes hard to know right from wrong, so God will give us a guide, the Holy Ghost. The Gift of the Holy Ghost is also called Baptism by Fire. After baptism with water we can receive the Baptism by Fire, (light the top of the tea bag tube).
If we listen to the Holy Ghost ,do the things we are prompted to do, and continue to repent with the sacrament, we can go up to live with our Heavenly Father again, (the tube will burn down and become a very fragile ash, because it is hot it will float up).
