Part II. WHY DO PEOPLE BECOME BITTER?
When the Lord doesn't do things just the way some people want Him to, they get bitter against Him. They get upset and angry at the Lord because He didn't do just exactly what they wanted Him to do. They're obviously lacking in faith and not trusting God, that He knows what's best.
