Simple

“And great crowds came to him, bringing with them the lame, the blind, the crippled, the mute, and many others, and they put them at his feet…” (Matthew 15:30)

Jesus was available. And he was powerful.

So word spread.

But ultimately, the people didn’t come because of this. Instead, they came because of how the verse ended:

“…and he healed them.”

They came because his product worked.
