The gospel we present has eternal consequences. If it is the true gospel, it can direct men and women into the everlasting kingdom. If it is a corrupted message, it can give unsaved people false hope while consigning them to eternal damnation. This is not a trivial matter for theologians to speculate on. It is an issue every lay person must understand and get right.
~ John MacArthur
The reason for saying, “when consistently worked out,” is because I think it is possible to inconsistently deny the truth of imputation while embracing other aspects of the gospel (blood bought forgiveness, and propitiation, for example), through which God mercifully saves.
I am thankful that God is willing to save us even when our grasp of the gospel may be partial or defective. None of us has a comprehensive or perfect grasp of it.
~ John Piper (This was a clarification of his tweet on praying for a new pope.)
One of them is completely wrong and it's not John MacArthur.
What is Justification? As John MacArthur notes:In its theological sense, justification is a forensic, or purely legal, term. It describes what God declares about the believer, not what He does to change the believer. In fact, justification effects no actual change whatsoever in the sinner's nature or character. Justification is a divine judicial edict. It changes our status only, but it carries ramifications that guarantee other changes will follow. Forensic decrees like this are fairly common in everyday life.
