Yeah, Emily, you can hate him if you want. You can do whatever you want, when you want ... I'm telling you how to have peace and joy in your life.
Otherwise, 50 years from now when you're at your grandkids' college graduation, you'll still be hating Kevin as the two of you watch your grandchildren together, hating each other.
Go ahead and lead your life of hatred and bitterness, Emily. It won't make you any happier than you are now, because hatred and happiness are not compatible. Hatred is only compatible with bitterness.
The LORD is near to all who call on him, to all who call on him in truth." (Psalm 145:18)
