"Sillimanite" is a word in ENGLISH

We can ignore even pleasure. But pain insists upon being attended to. God whispers to us in our pleasures, speaks in our conscience, but shouts in our pains: it is His megaphone to rouse a deaf world....No doubt pain as God's megaphone is a terrible instrument; it may lead to final and unrepented rebellion. But it gives the only opportunity the bad man can have for amendment. it removes the veil; it plants the flag of truth within the fortress of the rebel soul.
