Who are the people that consider the Lord to be slow?
2 Peter 3:9 (ESV)
9The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance.
The some is most likely a reference to false teachers, those who lack an understanding of God’s ways and his nature.1
