Romans 3:25

God presented Jesus as the atoning sacrifice [for our sins] through [our] faith in His blood [i.e., His death on the cross]. This was in order to demonstrate His justice when, by using forbearance, He passed over people's sins in previous generations.

Luke 23:34

Then Jesus called out, "Father, forgive these people [i.e., the ones responsible for crucifying Him], for they do not know [i.e., realize] what they are doing." Then the soldiers [See John 19:23] divided Jesus' clothing among them by gambling for them.

Acts 13:39

and [it is] by Him that every believer is made right with God in every way that he could not have been made right by [observing the requirements of] the law of Moses.

Hebrews 2:17

So, for this reason, He had to become like His brothers in every way [i.e., except that He never sinned], so that He could become a merciful and faithful Head Priest in things related to God's [service], [and] that He could provide a means of purifying [Lev. 16:30] for people's sins [i.e., make atonement for them].

1 John 2:2

And He is the One who provides a "covering over" [or atonement] for our sins [See Heb. 2:17; Dan. 9:24; II Chron. 29:24], and not for ours [who are already Christians] only, but also for the sins of the people of the whole world.
