The man from whom the demons had gone out begged to go with him, but Jesus sent him away, saying, 39 ‘Return home and tell how much God has done for you.’ So the man went away and told all over the town how much Jesus had done for him.
15 But in your hearts revere Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect.
