By this all people will know that you are my disciples, if you have love for one another.”
Consider this, there are many Greek words for love. Godly love, agape, is the most pure love and it is this love that Jesus is teaching to His disciples. If the world can see that we, the children of God, love one another with this perfect love, it is the love of God being demonstrated by imperfect humans.
From the viewpoint of an outsider who does not know the love of God our love might look like one or more of the other types of love. Love of family and love of friends is common in the world. We even have that love within the family of God. What sets us apart is when we open up our community to unbelievers and show them how God loves us through each other when one of our members acts out of character.
- 1 Corinthians 6:15
Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and make them members of a prostitute? Never! - 1 Corinthians 12:12
One Body with Many Members
For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ. - 1 Corinthians 12:18
But as it is, God arranged the members in the body, each one of them, as he chose. - 1 Corinthians 12:25
that there may be no division in the body, but that the members may have the same care for one another. - 1 Corinthians 12:27
Now you are the body of Christ and individually members of it.
Paul’s first epistle to Corinth is a prime example of how he reminds us who we are and how we are to act. Why does he have to remind us if we are all members of the same family?
For it has been reported to me by Chloe’s people that there is quarreling among you, my brothers.
Families quarrel from time to time. Who is going to settle this? Paul brought the gospel to Corinth and set in place a structure for the church that begins with oversight. We are all answerable to a higher authority and when local leadership cannot resolve certain issues those who showed agape love to begin with are called back to settle their disputes. Submission is required.
