How do we know that Christ's incarnation is true?

The truth of Christ's incarnation is confirmed by both Old Testament prophecies and New Testament declarations. Prophecies such as Isaiah 7:14, which speaks of a virgin giving birth, set the stage for the coming of the Messiah. The New Testament, particularly in John 1:14 and 1 John 1:1, provides direct witness to His incarnation, stating, 'We beheld His glory.' These assertions by the apostles and their firsthand experiences cement the truth that Jesus is indeed God incarnate, our Savior who took on human flesh.
