Watch out for your great enemy, the devil. He prowls around like a roaring lion, looking for someone to devour. 
1 Peter 5:8

Don’t tear apart the work of God over what you eat. 
Romans 14: 20

So now I am giving you a new commandment: Love each other. Just as I have loved you, you should love each other. Your love for one another will prove to the world that you are my disciples. 
John 13: 34 – 35
