From Day 32:
The root problem is sin, not that of others, but our own. We fear judgment because we have judged; we have placed blame (judgment) upon those we perceive to have contributed to our unhappiness...
...resentment toward other people is not a flag for an area in which we do not love God as we should, it highlights an area in which we do not obey God as we should. Lack of obedience is sin, and it is sin—our own, not that of other human beings—that separates us from an awareness of God’s abiding presence with us.
The remedy for disobedience is discipline, not a discipline of our own making, but submission to the Lord’s lead.
Do not fear the voice of His rebuke; His discipline cleanses.
