Biblical Brutality

1 Kings 18
37 Hear me, O LORD, hear me, that this people may know that thou art the LORD God, and that thou hast turned their heart back again.
38 Then the fire of the LORD fell, and consumed the burnt sacrifice, and the wood, and the stones, and the dust, and licked up the water that was in the trench.
39 And when all the people saw it, they fell on their faces: and they said, The LORD, he is the God; the LORD, he is the God.
40 And Elijah said unto them, Take the prophets of Baal; let not one of them escape. And they took them: and Elijah brought them down to the brook Kishon, and slew them there.

Matthew 25
30 And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth.

I am struck by Old Testament and New Testament brutality. But, then again, we know that life is, at times, harsh.
