What does Luke 6:18 mean?
This describes Jesus' experience at least since He healed the man with leprosy. That man rejected Jesus' command to show himself to the priests, instead telling everyone he knew of the miracle (Luke 5:12–16). He has been telling stories of how Jesus' miracles, actions, and teaching separated His main followers from His detractors. Now, Luke focuses on how Jesus attracts the multitude: by healing them, freeing them from demons, and keeping them engaged in His teaching.Teaching is why Jesus came (Mark 1:38). As with the prophets of the Old Testament, His lessons explain how people can come to a saving relationship with God. The last of the Old Testament-era prophets was John the Baptist who called for repentance and holy living. Jesus demands His followers' lives in return for eternal life through Him. He gives details in Luke 6:27–49.
Jesus performs miracles and acts of healing for three distinct reasons. The primary reason is that the display of God's power validates the teaching of God's message. Another is to validate the faith people have in Him (Mark 5:34; 6:5–6; Luke 5:20–25). A third is compassion. Sometimes Jesus just feels sorry for people and wants to ease their burdens (Matthew 14:14; Luke 7:12–15).
Finally, Jesus expels demons. Jesus encounters a substantial number of people possessed by demons; the Bible doesn't explain why. Most likely, the demons are both trying to thwart Jesus' plans and are oddly drawn to Him. It's important to note that although Jesus and some of the church leaders exorcise demons (Luke 6:18; Mark 6:13; Acts 5:16; 8:7), nowhere in the New Testament are believers commanded to, nor are we given instructions as to how. The Bible doesn't even tell us how to differentiate between demon possession, mental illness, and physical illness.
What we can learn from Scripture is how to prevent demon possession and oppression. Avoiding demon possession is simple: become a Christian. When we trust Jesus for the forgiveness of our sins, the Holy Spirit dwells in us permanently. He will not allow demons to live with Him in us. The way to avoid demonic oppression is to follow God's standards in Scripture, starting with His commands against activity that draws the attention of or actively calls demons. This includes playing Ouija boards, visiting psychics, and performing foolish spells promoted on social media and websites. Gathering herbs, lighting candles, and saying things "with intention" is not a means of honoring anything. It's a way to invite demons into your life.
