That is very good insight.
WHen I was training as a hospital chaplain, by supervisor, blessings be upon his soul, told me to make sure I knew what my expectations were before I made a "call", so that I wouldn't be thrown when they weren't met.
There's nothing like needing something to be true to get in the way of seeing how it is and how it isn't. You've got to hand ourself over to God, expectations and all, and tell Him to take charge before you go researching the Bible. Otherwise it can be little more than an inkblot in which you see only what you brought.
May God forgive me all the times I started telling Him what His Word says. And may He be praised forever for all the times he yanked my chain and said, "Not so fast, buster."
