How do we know God will not cast away a perfect man?

The notion that God will not cast away a perfect man is supported by a deep understanding of God's justice and grace. Job 8:20 states, 'Behold, God will not cast away a perfect man,' emphasizing that God has a commitment to His children who are found perfect in Christ. As 1 John 3:5 reveals, Jesus was manifested to take away our sins, and in Him, there is no sin. Thus, those who are in Christ are viewed as righteous in the eyes of God. This perfect standing is not based on personal merit but on Christ's obedience and righteousness credited to believers.
