This place where men must go after death to purge their sins is an invention of religion. The word purgatory comes from the word purge, and the Bible says that Christ “by Himself purged our sins” without any help from us (Heb. 1:3).
The Lord told the dying thief, “To day shalt thou be with Me in paradise” (Luke 23:43). This is significant, since the inspired Word of God calls this man a thief, and it was his own testimony to the other thief that “we receive the due reward of our deeds” (v. 41). That is, he was admitting he had not been framed or misjudged, but had indeed committed crimes worthy of the death penalty. If there was a Purgatory, this man would have gone there, yet we have the Lord’s word on it that he did not.
If anyone needed to go to Purgatory, it was the carnal Corinthians! Yet Paul told even these sinful believers that they could be “confident” that “to be absent from the body” is “to be present with the Lord” (II Cor. 5:8). Because of the perfection, completion, and sufficiency of Jesus’ sacrifice, we are immediately in the Lord’s presence after death, fully cleansed, free from sin, glorified, perfected, and ultimately sanctified.
Jesus suffered for our sins so that we could be delivered from suffering. To say that we must also suffer for our sins is to say that Jesus’ suffering was insufficient. To say that we must atone for our sins by cleansing in Purgatory is to deny the sufficiency of the atoning sacrifice of Jesus (1 John 2:2). The idea that we have to suffer for our sins after death is contrary to everything the Bible says about salvation. source 1 source 2
