How do we know the doctrine of Christ's nature is true?

The doctrine of Christ's dual nature as fully God and fully man is rooted in the Bible, particularly as seen in Matthew 1:20-23, which states that that which is conceived in Mary is of the Holy Ghost and refers to Jesus as Emmanuel, God with us. This aligns with Galatians 4:4, explaining that God sent His Son, made of a woman, under the law, indicating His human nature. Furthermore, the New Testament declares Jesus' divinity and uniqueness through His actions and His fulfillment of prophecy. The revelation of Christ's nature comes through the work of the Holy Spirit in the hearts of believers, affirming the trustworthiness of this doctrine. The mysteries of faith, such as the virgin birth, compel us to believe in God's omnipotence rather than to rely solely on human understanding.
