'Love' in the Bible

But I have [this] against you: that you have left your first love.

'I know your works, and your love, and faith, and service, and patient endurance--and your last works [are] greater than the first.

As many as I love, I reprove and discipline. Be zealous, therefore, and repent!

And they conquered him by the blood of the Lamb and by the word of their testimony, and they did not love their lives until death.
