In this Healing School session, Justin continues a series on doubt, specifically addressing how it arises from the devil's attempts to use circumstantial evidence and arguments to contradict God's promises, as outlined in James 1:5-7, which advises asking God for wisdom without doubting. Justin stresses that doubting equates to siding with the devil against God, urging listeners to trust and believe in the scriptures to overcome doubt, rather than entertaining opposing theories or reasons. He encourages envisioning a healed future based on Biblical truth, not circumstantial predictions, and defines doubt as a hesitation or opposition to God's truth, which can be overcome by confessing and repenting from it, allowing God's forgiveness to cleanse unrighteousness.
