Everyone who hates his brother is a murderer, and you know that no murderer has eternal life present in him.
– 1 John 3:15 (International Standard Version (©2008))
Before you were saved it was so easy to say, “I hate that person for what they did to me” but once the Blood of Jesus washed your sins away when you didn’t deserve it, that hate had to be let go. If you want to hate someone then hate the devil who inspired that evil that was done against you.
