1 John 3:17-18

3:17 But whoever has the world’s possessions and sees his fellow Christian in need and shuts off his compassion against him, how can the love of God reside in such a person?

3:18 Little children, let us not love with word or with tongue but in deed and truth.

1 John 3:12

3:12 not like Cain who was of the evil one and brutally murdered his brother. And why did he murder him? Because his deeds were evil, but his brother’s were righteous.
