How do we know that Jesus Christ fulfilled God's promises?

The fulfillment of God's promises is clearly seen in the person and work of Jesus Christ. As the promised Messiah, He perfectly satisfied the requirements of the law through His sinless life, offering Himself as a perfect sacrifice for sin. His resurrection from the dead not only validated His claims about Himself but also assured believers of their future resurrection and eternal life. As stated in Hebrews 1:1-3, God spoke through His Son, affirming that Jesus is the heir of all things and the exact representation of God's being.

Moreover, the prophetic writings throughout the Old Testament indicated a coming Redeemer, and Jesus' life matches these predictions in every detail. His birth, ministry, death, and resurrection are fulfilling events that reveal God's intention to save His people. Therefore, believers can have unwavering confidence in the promises of God, as fulfilled in Christ Jesus, assuring their salvation and eternal hope.
