If you have love for one another...
35 By this all will know that you are My disciples, if you have love for one another. (John 13)I looked up the word "love" that is used in this passage.
It is the word agape¯
Thayer defines it: 1) brotherly love, affection, good will, love, benevolence
So is Jesus saying that people who are kind to one another - who have good will toward one another - benevolence - will be thought of as his disciples? Or is He saying that if you claim to be a follower of his and you don't exhibit this agape, then it will be questionable to "all men" that you really are his disciple?
Either way, we should love one another. Because ... if you bite and devour one another, beware lest you be consumed by one another! (Galatians 5:15)
