I’m not sure what causes a person to be open-minded.
Certainly rejecting fear would help.
Relieving yourself of the conviction that you and all your co-horts possess the only answers would also be beneficial.
But in the Good Book, there is the story of a centurion. He has a servant. Now, we know the centurion is in charge of a hundred men, which
means he’s been given some rank and confirmation of the authenticity of his ability. So why would such a fellow be concerned about a servant? How would that relationship have sprouted?
We know that the gentleman was not only a commander, but was also open to the idea that opportunities can come from unlikely places. So rather than having a servant who hates you, why not have one who loves you?
But when that servant becomes sick and you realize that all those possessing medical knowledge who surround you are inept in advancing a cure, then it becomes necessary to use your open mind to consider a more unorthodox option.
How about an itinerant preacher from Nazareth, who is disrupting his religious community, but supposedly has healing in his hands?
The centurion did not allow his sense of Roman superiority to overwhelm him, leaving him without a remedy. He sent a messenger to ask Jesus to heal his servant. When Jesus started to head his way, the centurion was sensitive enough to realize that if this Nazarene came into his home, the young man would be considered unclean because he was at the hearth of a heathen.
So the centurion told Jesus just to say the word, and the servant would be made well. After all, as a centurion, he did that all the time with his soldiers. “You go do this. You go do that.”
Jesus was impressed. He said, “Never have I seen so great a faith.”
So maybe the definition of faith is when we realize we don’t have anything to lose, so being open-minded about other choices just might be life-saving.
