Mark 1 and 2 Devotional

Todays devotional is brought to you by Luke Langman.
Can you guess which piece of machinery that he is using while giving us this word?
Mark 1:
36 Simon and his companions went to look for him, 37 and when they found him, they exclaimed: “Everyone is looking for you!” 38 Jesus replied, “Let us go somewhere else—to the nearby villages—so I can preach there also. That is why I have come.” 39 So he traveled throughout Galilee, preaching in their synagogues and driving out demons.
Mark 2:
On hearing this, Jesus said to them, “It is not the healthy who need a doctor, but the sick. I have not come to call the righteous, but sinners.”
