Passover in the Old Testament was deliverance for God's people in Egypt. It describes how a lamb was sacrificed by each family to save the people of God from bondage and death. In the New Testament, the sacrifice of Christ saves believers from the wages of sin and death (Romans 6:23). Believers can testify, "Christ our Passover was sacrificed for us"(1 Corinthians 5:7).
Christ sacrificed for us takes away all our sins. Christ made the sacrifice in the place of every believer. This is the substitutionary atonement. The sacrifice of Christ is effectual to take away all the believer's sins (1 John 1:7).
The sacrifice of Christ justifies believers from all sin. Religion without the sacrifice of Jesus Christ can never take away our sins. Our works can never be enough to pay for our sins. God has provided the way, and the only way, for every believer's sin to be forgiven, only through the sacrifice of Jesus Christ.
"For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life" (John 3:16). Jesus Christ our Passover is given by God the Father to all who believe (John 3:16). Christ was sacrificed for the sins of all who believe.
God is calling out his people from every nation. The sacrifice of Jesus Christ redeems believers to God "out of every tribe and tongue and people and nation" (Revelation 5:9). Christ our Passover is every believer's sacrifice for sin.
