In this Healing School lesson, Justin emphasizes the importance of resisting doubt, which he identifies as an enemy to faith. He begins with 2 Corinthians 12:7, where Paul describes a "thorn in the flesh" as a messenger of Satan sent to harass him due to his abundance of revelations, clarifying that this was not a physical ailment but a demon spirit meant to obstruct his understanding of God’s promises.
Justin explains that the enemy uses doubt to rob believers of healing promises, as seen in Mark 4, and stresses that not all healing is instantaneous—sometimes it’s a process. He encourages steadfast faith, drawing from James 1:5-7, which warns that doubting prevents receiving from God, and 2 Corinthians 10:3-5, which urges believers to cast down arguments and reasonings that contradict God’s word. Ultimately, Justin asserts that doubt is the result of losing an argument against God’s truth, urging believers to use scripture as a weapon to stand firm and resist the devil’s lies, reinforcing that God’s grace is sufficient for victory.
