How do we know that Jesus could not sin?

The question of whether Jesus could sin arises from a misunderstanding of His dual nature as fully God and fully man. In the sermon, it is emphasized that Jesus is divine and thus cannot sin, as God is holy and cannot contradict His nature. Quoting 1 John 3:9, it is clear that just as believers, when born of God, cannot sin, so too did Jesus, being the Son of God, always remain without sin. His temptations were real, but they did not stem from a sinful nature; instead, they were permitted by God to fulfill His divine plan of salvation.
