Apparently love has a lot to do with everything – shopping, driving, living or being. Love is both something that "feels good" and something that we experience. It can be both a noun and a verb – a "thing" and an action. Actually, the word is rooted in more than one word, but in english we end up with the usual confusion. Maybe that's why we have so many problems understanding one another.
Suffice it to say that without a course in other languages, some of us have a requirement to "love one another." Those words were spoken by Jesus 2000 years ago, and their demands have never diminished. Jesus was talking about giving ourselves up for one another – doing for when we don't feel like it or don't like being "there" or have to give up our time or money.
He even tied it to "being a servant" when he got down on the floor and washed his disciple's feet. Remember, He was the "Master". He was the boss. Yet, instead of commanding His followers to come wash the dust off His feet He did for them. You can check it out yourself in John 13 (read the whole chapter).
What brought me to this point was the second half of First John, chapter 3 where he says "we should love one another;" and then he follows in verse 18 with "love…in deed and truth." Love here and in John 13 was action, not some weakness of heart or soft music but actually doing something for someone else. BTW, take a close look at verse 17.
Another time I'll tackle "love your neighbor" vs "love one another." There is a difference.
