[Satan] said to [Jesus], “If You are the Son of God, throw Yourself down. For it is written: ‘He shall give His angels charge over you,’ and, ‘In their hands they shall bear you up, lest you dash your foot against a stone.’”
Satan’s attacks against Job were two-fold. First, Satan destroyed Job’s children and property (Job 1-2). Those attacks were directly against Job himself. The second stage—Job’s struggle to maintain his confidence in God—was longer, more subtle, and more indirect: as evidenced by Job’s wife’s challenge: “Do you still hold fast to your integrity? Curse God and die!” (Job 2:9). There is no direct evidence that Satan inspired Job’s wife’s words, but given his proximity to the situation, it is reasonable to assume it was part of his overall attack.
Which is more advantageous to Satan—to make you uncomfortable in the short term or to destroy your long-term confidence in the love and faithfulness of God? Obviously, the latter. When Satan tempted Jesus in the wilderness, his second temptation was an attempt to negate Jesus’ trust in God’s care.
If Satan can convince you that God doesn’t love you, forgive you, or care for you, he will have neutralized your faith.
I must have complete, absolute confidence in God and no confidence in myself.
