What does it mean to confess that Jesus Christ has come in the flesh?

Confessing that Jesus Christ has come in the flesh is a fundamental Christian doctrine that acknowledges His dual nature as both fully God and fully man. This confession is essential for understanding the gospel, as it affirms that Christ was sent by God to save a specific people from their sins, as noted in Matthew 1:21. The Gnostic heresy, which denied the true humanity of Christ, attempted to undermine this crucial element of the faith by suggesting that God could not truly take on human form. By affirming the incarnation, we recognize the reality of Christ's life, death, and resurrection, which are central to our salvation. This belief isn't just theological; it has profound implications for how we understand God's justice and mercy in relation to sinners, as Christ took on our sins and provided the way for us to be reconciled to God.
