1 John 2:8-11 ESV
At the same time, it is a new commandment that I am writing to you, which is true in him and in you, because the darkness is passing away and the true light is already shining. Whoever says he is in the light and hates his brother is still in darkness. Whoever loves his brother abides in the light, and in him there is no cause for stumbling. But whoever hates his brother is in the darkness and walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes.
Hate is a sign of darkness. It is the opposite of love and life. It is the mark of one that does not know God. Where you see hate, there you see the fruit of Satan and is a mark of the beast.
