Romans 5:6-11
For while we were still helpless, at [just] the proper time, Christ died for ungodly people.
Romans 5:15-21
But the free gift [of salvation through Christ] is not [exactly] like the sin [of Adam]. For if many people died [physically] because of the sin of the one man [i.e., Adam], how much more did God's favor abound by [providing] His gracious gift [of salvation] to many people because of the one man, Jesus Christ.
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.
Hebrews 12:24
and to Jesus, the Mediator of a New Agreement [between God and mankind], and to the sprinkled blood [of Jesus], which says better things [to us] than [the blood of] Abel did. [Note: The contrast seems to be that "Abel's blood called for vengeance and death (See Gen. 4:10) whereas the blood of Christ provides mercy and life"].
1 Peter 1:2
These people have been [specially] selected, and [their acceptance was] pre-planned by God the Father, and they were set apart through [the work of] the Holy Spirit. This resulted in their obedience and sprinkling [Note: This is a figurative reference to the Old Testament practice of cleansing, See Exodus 24:7-8] by the blood of Jesus Christ. May God's unearned favor and peace be continually upon you.
1 Peter 2:24
Jesus took upon Himself our sins [when] His body was placed upon the cross so that we, [through] dying to [i.e., giving up] the sinful life, would live for righteousness. You were healed [from your sins] by His being brutally treated.
1 Peter 3:18
For Christ suffered once for people's sins [to be forgiven]. [It was the case of] a righteous Man suffering for unrighteous people, so that He could bring you [or, "us"] to God [for salvation]. [Though] He [i.e., Jesus] was put to death physically, He was brought back to life by the Holy Spirit [Note: Some translations say "in spirit"].
