Commands

I've never seen love described as anything other than an emotion. That's how it's always portrayed, at least. It's something that comes upon you, that's out of your direct control. It's said it's like a narcotic, or even a being unto itself. You are under its influence, and the rest of you is just along for the ride.

This is my command: Love each other.
John 15:17

How then, can love be commanded? Moreover, how can you be commanding of any of your emotions?

Be cheerful no matter what.
1Th 5:16

Or.

Know this, my beloved brothers: let every person be quick to hear, slow to speak, slow to anger.
James 1:19

I'm not sure I have an answer for this. In fact I know I don't. What I don't understand about myself is that I decide one way, but then I act another, doing things I absolutely despise. So if I can't be trusted to figure out what is best for myself and then do it, it becomes obvious that God's command is necessary. (Romans 7:15-16)
