1 John 3:12-20

12Do not be like Cain, who belonged to the evil one and murdered his brother. And why did he murder him? Because his own actions were evil and his brother’s were righteous. 13Do not be surprised, my brothers and sisters, if the world hates you. 14We know that we have passed from death to life, because we love each other. Anyone who does not love remains in death. 15Anyone who hates a brother or sister is a murderer, and you know that no murderer has eternal life residing in him. 16This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers and sisters. 17If anyone has material possessions and sees a brother or sister in need but has no pity on them, how can the love of God be in that person? 18Dear children, let us not love with words or speech but with actions and in truth. 19This is how we know that we belong to the truth and how we set our hearts at rest in his presence: 20If our hearts condemn us, we know that God is greater than our hearts, and he knows everything.
