Luke, chapters 8 & 9

“And the Twelve were with him, as were certain women who had been cured of wicked spirits and sicknesses: Mary who was called Magdalene, from whom seven demons had come out […].”
~Luke 8:1,2

“As Jesus got out onto land, a demon-possessed man from the city met him. For a considerable time he had not worn clothing, and he was staying, not in a house, but among the tombs.”
~Luke 8:27-36

How does a person succumb to demon possession and why did it seem to be so commonplace in Jesus’ day?
Insight On The Scriptures” defines it as “the captive control and influence of a person by an invisible wicked spirit.”
That influence may manifest itself physically, emotionally or mentally through the victim.
Luke’s account demonstrates that it is possible for a person to be possessed by more than one demon, and it is possible for a demon to possess an animal.
When a person opens a portal into the occult, be it by superstitious practices, trying to communicate with the dead, diabolic entertainment, or through witchcraft, he makes himself vulnerable to demon possession.
In the case of King Saul, a demon began to attack him when he became arrogant and defiant in his service to Jehovah and lost God’s holy spirit. (1 Sam. 15:10,11,22,23; 16:14-16,23; 18:10-12)
When Jesus walked the earth, many Jewish leaders in particular had strayed from true worship and their attitude was heavily influenced by demons. (John 8:44)
Modern Christians do not practice exorcism, which tends to combine rites and chants or a combination of words, as if a person could be liberated from demons through magic.
Rather, they put on “the complete suit of armor” of Christian lifestyle and outright reject evil practices. (Eph. 6:11-18; Jas. 4:7)

Isaiah, chapters 63-66

“But you are among those forsaking Jehovah, {…}
Those setting a table for the god of Good Luck,
And those filling up cups of mixed wine for the god of Destiny.”
~Isaiah 65:11

What is luck?
Some dictionaries define it as a force that operates for good or ill, or chance considered as a force that causes good or bad to happen.
Is the belief in a supernatural force that affects our circumstances in line with God’s way of thinking, as outlined in the Bible?
In ancient times, Luck and Destiny were pagan gods.
Their worshippers traditionally celebrated a party for them on the last day of the last month of the year, where they feasted and drank wine in their honor. (Insight on the Scriptures, vol. I, “God of Luck”)
For a dedicated servant of Jehovah to request a favor, or blessing, from a force other than Jehovah himself, is a form of betrayal. (De. 10:20; Luke 4:8)
The reliance on luck through customs or charms is a superstitious form of Spiritism, a belief that encompasses the practices used to invoke forces or spirits other than Jehovah (demons).
This belief is in direct conflict with true worship. (De. 18:10,11; Is. 8:19,20; Gal. 5:19-21)
Although it seems inoffensive and even polite to wish someone “good luck,” those pleasing Jehovah adjust their thinking to his point of view and take into account his feelings on the matter, knowing all blessings come from him alone in due time. (Is. 65:16,17,24)
