Good thing Jesus didn't do any mumbo jumbo
"Go," he told him, "wash in the Pool of Siloam"
May I, in love, suggest you read a few scriptures for yourself to see what Jesus had people do as a way of activation of faith.
For we know….faith without works is dead.
And again, be careful to not quibble over words to the ruin of many hearers.
Also that we be careful not to snuf out the faith that others might have with our own vast throngs of theological knowledge and might.
