I seem to have missed addressing this.
It's a relevant point, God CAN do anything as His Word says, but He doesn't.
In context, Jesus was speaking to the 12 apostles about who they will be persecuted by. Who He was referring to were those in v16-25 that would be their persecutors. Ultimately He was assuring them that God was in control, despite what they may perceive in their missions. It was God who was in TOTAL control of not only their welfare, but what they would even say. He contrasts the impotence of those people to what god can ultimately do.
This injunction to fear God and not people is perhaps a development of
Is. 8:12,
13. It is supported by three arguments: first, the acts of the wicked will be shown for what they are; second, although people can kill the body, God can punish soul and body; and third, God orders everything, down to the fall of a sparrow and the number of hairs on the head. The Bible consistently teaches that fear and reverence are appropriate responses to God.(RSB)
I understand exactly WHAT you are saying, I'm juts not accepting it. Sorry if my straightforwardness offends you but I'm more concerned with rightly dividing God's Word, than making people who espouse false teachings to feel all warm and fuzzy.
