Christian! Take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares. (Luke 21:34)
'That day' is the day of the Lord's coming. The Bible describes that day to be a terrible day. The day when all souls will give an account.
It is not wise to consider yourself to be above or just 'saved' enough to regard this warning.
Under God, answer this question - what are you 'saved' from? And what is the source of your salvation?
