Mathew 15:30

And great crowds came to Him, bringing with them the lame, crippled, blind, mute and many others, and they put them down at His feet; and He healed them.

Jesus never refused to heal then, and He doesn’t refuse to heal now.  How did these people know to bring these people to Jesus for healing?  Because they heard Jesus’s message and saw Him work miracles.  We can still hear the message of healing in the bible and see Jesus’ work miracles in our lives.
