Scripture supports the claim that Christ made one sacrifice that will be adequate forever.

Hebrews 10:11-18

11 As every Jewish priest stands daily in front of the altar, he performs rituals and offers the same kind of sacrifices that could never remove the guilt from anyone who sinned [MTY]. 12 But Christ offered a sacrifice that will be adequate forever, and he offered it only one time! Then he sat down to rule with God at the place of highest honor [MTY]. 13 From now on, he is waiting for God to completely subdue all Christ’s enemies [MTY]. 14 By offering himself once, he has provided that those whom God has set apart will be eternally made ◄perfect/all that God intends them to be►. 15 The Holy Spirit also confirms to us that this is true. First the Lord says:

16 When the time [MTY] when the first covenant that God made with my people has ended,

I will make a new covenant with them [MTY].

I will do like this for them:

I will cause them to understand my laws

and I will cause them to obey them (OR, enable them to know them sincerely).

17 Then the Lord said:

I will forgive them for their [DOU] sins,

and I will consider that they are no longer guilty for having sinned.

18 When God has forgiven someone’s sins, that person does not need to make any more offerings to atone for his sin!
