What is false assurance according to the Bible?

False assurance can be exemplified by Micah's belief that he would receive blessings from God because of his own works, such as creating idols and hiring a Levite. This misguided confidence leads individuals to trust in their deeds rather than the crux of the Gospel, which centers on the work of Jesus Christ. True assurance is firmly grounded in faith in Him, as seen in Ephesians 2:8-9, whereas false assurance often relies on subjective feelings or human standards, producing a false sense of security. This is a significant distinction for Christians as they navigate their faith and seek the assurance that only comes from God.
