How do we know Jesus Christ is our offering to God?
Answered in 1 source
Jesus Christ is recognized as our offering because He is the only one without blemish who fulfills God's requirement for righteousness.
Scripture indicates that all offerings to God must be without blemish, symbolizing purity. Jesus Christ, the last Adam, came as the holy God-man, fulfilling the requirements of a perfect sacrifice. He offered Himself voluntarily and without sin, which is essential for acceptance before God. Moreover, it is only through faith in Christ that we can be accepted by God, because all our righteousness and holiness come through Him. The offerings described in Leviticus foreshadowed the ultimate sacrifice of Christ, which is why He is the only offering that God will accept for our atonement.
