Hebrews 7:27
He does not need to offer up [animal] sacrifices every day like those head priests did [Note: The head priest here is represented as being in charge of the daily sacrifices offered by the other priests], first for His own sins and then for the people's sins. For He did this once for all time when He offered up Himself [on the cross].
2 Corinthians 5:21
God considered Christ to be sinful on our behalf, even though He never sinned, so that we could be considered right with God through Him.
1 Peter 2:5
And you yourselves are also like living stones, being constructed into a spiritual house. For you are like holy priests who offer spiritual sacrifices that are acceptable to God through Jesus Christ.
1 Peter 2:9
But you people are especially chosen [by God]; you are a royal body of priests; you are a nation especially set apart for God's use; you are a people who belong exclusively to God, that you may express the virtues of the One who called you out of darkness [i.e., of sin and error], and into His marvelous light [i.e., righteousness and truth].
