YES! God’s punishment = death.. nothing less than that.. Nahum 1:3 says “…the LORD will not leave the guilty unpunished…” punishment for both believers and unbelievers is death … Romans 6:23 say “…for the wages of sin is death…” but for a believer, God inculcates disciplining measures too… If you are a legitimate child, God will discipline.
eg: Paul says that since people mistreated the handling of the Lord’s supper, many of them were sick and put to rest..
Ananias and Sapphira were killed because of their pretension.
