From the series Strongholds: Marijuana and The Church:What should we do?

The body and soul are subjected to the fallen world while the spirit is God's when we give our lives to Jesus. If a Christian is not actively trying to redeem their body and soul through the reading of the Bible and walking in the ways of God, it is possible for this Christian to be demonized, or possessed by demons, since the person is allowing them to have spiritual ground, which could also be defined as a stronghold. A stronghold can also be any mindset that is contrary to God's Word. A person can allow strongholds in by thoughts or feelings. If a person has an inner pulling toward a sin and moves towards it, it can become a stronghold. For complete deliverance, the demons must be cast out and the strongman, or the demonic leader that heads these demons, must be cast out. There is a biblical order in which this must be done. Family sometimes people don't get fully delivered because the demons are bound, but the strongman is allowed to stay. The way to identify and cast out the strongman is in the Bible. Family whenever one sees "the spirit of..." this is identifying what the strongman is. An example is in the passage Isaiah 61 where God promises to give the garment of praise for the spirit of heaviness. Another example is from Romans 8, identifying the spirit of bondage to fear.
