Seeing reality can be hard.
Have you ever tried to get someone to understand a truth, that he or she was convinced was incorrect? No matter how good we think our argument is, some people still will not believe that green is green, until they hear an argument
that hits their heart.
John Townsend, in "Hiding from Love," says that that we cannot expect people to understand more than they can actually understand at a given point in time.
"We can't 'do' something with what we don't have. To demand that people be more mature than they are is to place them under condemnation....Telling people to do things they don't have the ability to do is like ripping a child's security blanket away from him before he's ready to give it up. The child will panic, and frantically search for his comforting possession. Sometimes he may search for another blanket, or withdraw into a heartsick hopelessness."
Although a person may not listen at the time, you never know when a logical statement will finally be understood. I know there are times when, years later, I finally say, "Oh, NOW I get it." So the good argument should always be made, even when you don't see the fruit. "I planted the seed, Apollos watered it, but God has been making it grow." --1 Corinthians 3:6
In a TV show I watched recently, a man was suffering from something similar to Capgras syndrome, triggered by a car accident. When his beloved wife came into view, his sight told him that it was someone else. When he shut his eyes and heard her speak, however, he knew the truth, that it was her.
Maybe sometimes when we're seeing blue and someone else, a "safe" person, tells us it's green, we need to be willing to close our eyes and listen. Maybe reality is as close as that--listening with another sense.
