Satan steps up attacks during the holy days because observation of those days involves spiritual focus on God and removal of sin. Satan shows up to disrupt whenever spiritual growth occurs. Right after baptism Jesus was driven into the wilderness and tempted by Satan with no delay. Satan set out to separate righteous Job from God by taking away all that Job had. During a time of blessing for Israel Satan moved David to take a census that showed reliance on human strength. Satan appeared in the synagogue on the Sabbath to disrupt the teaching of Jesus. Satan played a long game by afflicting a woman for eighteen years until she was healed by Jesus on the Sabbath. Right before and during Passover Satan entered Judas to arrange the betrayal of Jesus. Satan watches for opportunities to pound a wedge between people and God. Satan observes conversations and seeks to exploit inner thoughts in order to accuse people before God. Submission to God followed by resistance causes Satan to flee.

Satan's methods of deception permeate virtually every book of the New Testament, though he is rarely named directly. In James 3, he is identified as the source of "earthly, sensual, demonic" wisdom that produces confusion, disorder, envy, and selfish ambition within the congregation itself. James teaches that a lack of peace is evidence of Satan's involvement, since God's wisdom—pure, peaceable, gentle, willing to yield, full of mercy, without partiality or hypocrisy—produces righteousness only in an environment of peace. Satan deliberately stirs disharmony because he knows righteousness cannot flourish amid confusion. In James 4, this pattern is traced to unlawful desires clashing among believers, showing that friendship with the world equals enmity with God, since Satan rules the world's value system. Satan's power lies in his invisibility, intelligence, and cunning, making believers vulnerable like unarmed people in a jungle. First Peter 5 counsels sobriety and vigilance against this "roaring lion," yet clarifies that he may only devour if permitted—his access requires human consent. Ephesians 4 warns against giving him a "foothold" through unresolved anger, showing that even legitimate emotions can become entry points for sin if unchecked. Luke 4 reveals that Satan's temptations are relentless and multifaceted, attacking even Christ's strengths, not merely weaknesses, and continuing "until an opportune time." Christ's threefold response—refusing materialism, refusing to lower God's standards, and refusing sensationalism—established a pattern of resisting through truth rather than compromise. Believers are called to a defensive posture: resisting, standing firm, remaining alert, since offensive weapons against an unseen enemy are limited. First John reveals that the decisive victory over Satan has already been won through Christ's sacrifice, expressed in the past tense: "you have overcome the wicked one." Satan's chief weapon is fear—fear of missing pleasure or self-satisfaction—as seen in Eden, where he removed Adam and Eve's fear of God's warning about death. Job, by contrast, resisted this same tactic despite extreme pressure. Believers are assured that the "evil one cannot touch" those kept by Christ, paralleling God's hedge around Job and Christ's prayer that His followers be kept from the evil one. Second Corinthians 10 identifies the real battlefield as the mind, where Satan plants thoughts, arguments, and reasonings that "exalt themselves against the knowledge of God." This is precisely how Adam and Eve fell, and how Peter unknowingly echoed Satan's reasoning when he resisted Christ's foretold suffering. Since Satan is fundamentally a liar with no truth in him, the only effective defense is unwavering confidence in and reliance upon God's truth, exemplified by Christ's use of Scripture against every temptation. Victory over Satan therefore rests on three certainties: the decisive battle is already won, God shields His children as He shielded Job, and believers must resist by clinging to divine truth against every thought that opposes it.
