1 Thessalonians 4:9-12 (NIV)
9 Now about your love for one another we do not need to write to you, for you yourselves have been taught by God to love each other. 10 And in fact, you do love all of God’s family throughout Macedonia. Yet we urge you, brothers and sisters, to do so more and more, 11 and to make it your ambition to lead a quiet life: You should mind your own business and work with your hands, just as we told you, 12 so that your daily life may win the respect of outsiders and so that you will not be dependent on anybody.
2 Timothy 2:22-23 (NIV)
22 Flee the evil desires of youth and pursue righteousness, faith, love and peace, along with those who call on the Lord out of a pure heart. 23 Don’t have anything to do with foolish and stupid arguments, because you know they produce quarrels.
John 13:34-35 (NIV)
34 “A new command I give you: Love one another. As I have loved you, so you must love one another. 35 By this everyone will know that you are my disciples, if you love one another.”
