Bitterness comes from being unwilling to forgive. Bitter people are small people. They are unsuccessful people. They are people who cannot move forward. They are people who believe that the personal wrongs against them are so great that they — the offended — are entitled to do to their offenders what they pray the Lord Jesus Christ will never do to them: refuse to forgive.
My two cents
On a personal note, I think I have work to do when it comes to undoing bitterness, living in the past, and unforgiveness. I am convinced by the quote’s point that much of it is an unwillingness to move forward, even if it’s painful or punishing to do so.
I’d like to be able to memorise all of my reassuring quotes, but over time, there are too many and my brain can only hold in so much (as a side note, this fact sounds more like predestination than free will).
I would think that Phillips’ quote is one of the more important ones in my cache to remember though. If I wasn’t subscribed to the emails he sends, I might have missed the quote altogether.
