Luke 10:17–20 (NKJV)
17 Then the seventy returned with joy, saying, “Lord, even the demons are subject to us in Your name.”Luke 10:17-20
18 And He said to them, “I saw Satan fall like lightning from heaven. 19 Behold, I give you the authority to trample on serpents and scorpions, and over all the power of the enemy, and nothing shall by any means hurt you. 20 Nevertheless do not rejoice in this, that the spirits are subject to you, but rather rejoice because your names are written in heaven.”
This passage follows logically the sending of the seventy with authority to do God’s work. When they returned, they rejoiced that they had power over demons to cast them out. He reiterated to them that He gave them power over animals, the power of Satan, and protection from all harm. But He then diverged from this line of blessing to remind them of what was really important. He reminded them that having their names written in heaven (being saved) was a much more important reason to rejoice. When you see the blessings of God being poured out, when you see a miracle in your life or an amazing healing, do not neglect to be thankful for the gracious miracle of salvation, as it is the greatest gift of all that a person can receive.
