The classic lie setup: "How is your day going?" The classic lying response? "Fine."
Not many of us go about murdering or visiting houses of prostitution; at least I hope not. But how many of us lie?
So what's the big deal about lying anyhow?
Revelation 21:7-8 He that overcometh shall inherit all things; and I will be his God, and he shall be my son. But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
I'd say that makes it a big deal. That little clause at the end "...and all liars", wow. How many of us were doing just fine until that last clause?
Just some food for thought.
