“The Lord is not slow about His promise, as some count slowness, but is patient toward you, not wishing for any to perish but for all to come to repentance” (2 Peter 3:9).
Federal Visionists love this verse because they think that God is wishing for all to come to salvation. Besides sounding universalist and a-reformed, this fails to maintain the elementary distinction between justification and sanctification.
The Reformed fatwa has always insisted that justification is by faith alone. All that happens afterwards is sanctification, which would include repentance.
Thus, the Lord is patient, not wishing for any to perish but for all to come to sanctification.
