Let love be genuine. Abhor what is evil; hold fast to what is good. Love one another with brotherly affection. Outdo one another in showing honor.
Love makes the culture of the church a pleasant place. It leads to unity, service, and honor holding the church together beautifully as the Body of Christ. We should be known by our love. Jesus said it was to be the way in which His disciples could be found in the world (John 13:35).
What these two verses say about that love helps us know what it looks like. It is genuine and from the heart. It is not fake or manufactured. We know this through the commitment we have to disdain what is evil and cultivate holiness with each other. You can't get any more "real" than when we keep each other accountable for godly lives... in love.
We are to love with a strong family loyalty. Brotherly affection is family love. You don't turn family down. You don't turn your back on them. You care BECAUSE they are family. You live together, share together, love together, struggle together, care for each other up or down together, and rejoice together in a family together. You share all the experiences of life as a family. Christian love is a family experience.
We must love with intense honor and respect. Each of us should seek to "out love" the others around us. We honor each other with our care, not out of duty, but out of the respect for God's kingdom that we see in His church. We honor King Jesus when we love each other as He loves us, respecting Him as we respect one another with His love.
