My husband is colorblind; so is my son. The difference between the two is that, while my son recognizes this deficiency, my husband refused to admit his limitation for quite awhile. My husband wanted to believe that a particular favorite shirt is navy blue. It is not. It is black. No amount of his understanding it to be blue will make it blue. The shirt is black. Sometimes he happens to wear something that looks fine with the black shirt - other times he looks like he got dressed in a dark room with his eyes closed. My son, on the other hand, allows his wife to pick out his clothes. And he looks fine, all the time.
We all suffer with a side-order of blindness. It causes us to believe things that are not true and not believe a bunch of stuff that is absolutely true. When we are in this position, life spirals out of control in confusing ways. These false beliefs and denials that we hold as truth cause us to take actions that do not produce the results we want.
The ONLY way I know to change this dynamic is by making a decision that requires our own certainty to stand down AND choose to trust God.
