Do you want to be healed?

I read this in The Book of Q or The Gospel of Thomas: “And if you enter a town and they receive you, eat what is set before you. Pay attention to the sick and say to them, 'God's kingdom has come near to you.' But if you enter a town and they do not receive you, as you leave, shake the dust from your feet and say, 'Nevertheless, be sure of this, the realm of God has come to you.'"
