He who cannot find time to consult his Bible will one day find he has time to be sick; he who has no time to pray must find time to die; he who can find no time to reflect is most likely to find time to sin; he who cannot find time for repentance will find an eternity in which repentance will be of no avail; he who cannot find time to work for others may find an eternity in which to suffer for himself.
