The Liberty Bell bears the message for mankind to, "Proclaim Liberty Throughout All the Land Unto All the Inhabitants thereof."
In short, it signals 'freedom', and Leah Still is now one step closer to being free of cancer and the constant treatment it requires. Leah has been undergoing her cancer treatment at the The Children's Hospital of Philadelphia, the city in which the Liberty Bell resides. Devon Still just posted this video of Leah ringing a bell that signals her final radiation treatment and coming one step closer to the freedom of beating cancer.
Leah's now 13-month battle with Stage 4 neuroblastoma appears to be nearing the end.
