1 John 3:14-18 New King James Version (NKJV)
14 We know that we have passed from death to life, because we love the brethren. He who does not love [a]his brother abides in death. 15 Whoever hates his brother is a murderer, and you know that no murderer has eternal life abiding in him.
The Outworking of Love
16 By this we know love, because He laid down His life for us. And we also ought to lay down our lives for the brethren. 17 But whoever has this world’s goods, and sees his brother in need, and shuts up his heart from him, how does the love of God abide in him?
18 My little children, let us not love in word or in tongue, but in deed and in truth.
