I am currently read this book and it has been really good.
Last night, I almost finished it but right before the last chapter, I fell asleep.
There is one part I read last night (don't worry, this isn't going to ruin it for you if you haven't read it) where the main character is talking with God about forgiving someone. God tells the character, "for you to forgive this man is for you to release him to me and allow me to redeem him."
The character later on asks God if it is okay that he is still angry with the person who wronged him. God replies "Absolutely!...But don't let the anger and pain and loss you feel prevent you from forgiving him and removing your hands from around his neck".
This is such a difficult thing for me to practice if I am angry and truly upset with someone but I know that God has covered me with his grace and love and today I pray that I would be able to extend that same grace and love to others, forgiving and allowing God to work.
