Matthew 7:21-23 refers to many, not all.
IF I stated Matt. 7:21-23 it should have been MARK 7:21-23. There is a similar almost identical statement in MATT. 15:18-20
BUT since you brought it up, YES, Matt. 7:21;23 applies to ALL of us as well. Either at the end of our lives or at the end of this wicked age, enmasse, ala Matt. 25's sheep and goat account or Paul's account of it at the end of 1 Cor. 15.
Funny how we chuck all the stuff that's seemingly against us huh? And then lay them on other people. What kind of method is that anyway?
Matt. 4:4, Luke 4:4, Deut. 8:3 ALL state quite the opposite of your claim, from Gods Own Lips
And yes, we all are still sinners and yes, our sin is still "of the devil," 1 John 3:8, Mark 4:15
SO, who says LORD LORD in that equation? IF you say people, you missed the point again.
Luke 4:41
And
devils also
came out of many, crying out, and
saying, Thou art Christ the Son of God. And he rebuking them suffered them not to speak: for
they knew that he was Christ.
Matthew 12:28
But if I cast out
devils by the Spirit of God, then the kingdom of God is come unto you.
IT is one of the most obvious matters of the Gospels, Jesus casting out devils from people. YET few believe it to be a fact for themselves. They think they are immune from the tempter in their own minds.
And NO ONE can be further from the truth of the matter. Interestingly ALL of these also want to see our neighbors burned alive forever or eternally annihilated.
Hmmmm? What's up with that I wonder....not
