How do you know from the New Testmanent that God may kill Christians who participate in interfaith dialogue and approval of other religions?

The New Testament reaffirms that God kills believers (born-again Christians) who participate in idolatry (interfaith dialogue), participating in the affirmation of other religions (“faiths”).  This is clear in I Corinthians 10:6-10:

These things took place as examples to keep us from craving evil things as they did.  Do not be idolaters, as some of them were. As it is written:  “The people sat down to eat and to drink, and got up to revel in idolatry.”  We should not commit sexual immorality, as some of them did, and in one day twenty-three thousand of them died.  We should not test Christ, as some of them did, and were killed by snakes.    And do not complain, as some of them did, and were killed by the destroying angel.”

I Corinthinans 10:10 confirms that there is a destroying angel who kills believers (born-again Christians) who participate in idolatry (interfaith dialogue).

The Ten Commandments are in effect in the New Testament Age of Grace, and in the Age of Grace, God will send His “Destroying Angel” to kill believers who participate in idolatry (religious pluralism and interfaith dialogue) as God did in the days of Ancient Israel.  The New Testament emphasizes that God’s angels will kill believers in the Age of Grace.

Anyone participating in proliferating religious freedom, religious tolerance, and interfaith dialogue are susceptible to the curses emphasized in I Corinthians 10:10 directed at Christian (born-again) believers.
