From a friend (LE):

After the covenant there's a part where God is speaking to those people who accepted. The first paragraph puzzled me:

"All you who have turned from your wicked ways and repented of your evil doings, of lying and deceiving, and of all whoredoms, and of secret abominations, 
idolatries, murders, priestcrafts, envying, and strife, and from all wickedness and 
abominations, and have come unto me, and been baptized in my name, and have received a remission of your sins, and received the Holy Ghost, are now numbered with my people who are of the house of Israel. I say to you..."

Notice it's all past tense. Those highlighted phrases and some of the others are pregnant with meaning for me from what I've gathered in scripture, and they involve a lot more than standing up and saying yes to four questions. And yet this presupposes these people have fulfilled those things. Either that or it's God's way of trolling them.

This is a great catch. It's another vindication in the answer of what a few in the movement have been saying. This clinches that the whole damn answer was a vindication of what we we've been saying.

I wonder if this is God's way of giving them a chance, but wrapping/binding them up with a timer saying "Here's your chance to do what you claim. Good luck. If not, you have just dug your own grave." A way of more quickly wrapping up this phase with Gentiles so He can move on to "finding a new people." Gentiles, to me, meaning Gentiles at heart. Paul: 

"For he is not a real Jew who is one outwardly, nor is true circumcision something external and physical. He is a Jew who is one inwardly, and real circumcision is a matter of the heart, spiritual and not literal" (Romans 2)

I'm going to re read the answer again and immediately I saw this: "Nevertheless people who are quarrelsome and proud are also among you, and since you seek to unite to become one people I answer you as one." If this from God, God is saying that they are the ones seeking this.
