What does the Bible say about the nature of Jesus Christ?

The Bible presents a profound mystery concerning the nature of Jesus Christ, affirming that He is both fully divine and fully human. Isaiah 9:6 prophesizes this dual nature by calling Him Wonderful, Counselor, the Mighty God, and the Everlasting Father. This means that while He was born as a child in Bethlehem, He is fundamentally the Eternal Son of God, existing with the Father from eternity. His conception was miraculous, born of a virgin, ensuring that He was without sin, fulfilling the need for a perfect Savior who could redeem humanity from sin and death.
