I already addressed your metanoia issue, but since you kept refusing to see that, I'll address some of it in further detail now. I shouldn't have to spoon feed everything when anyone can study Dispensationalism on their own, and I certainly am not obligated to do it on your timeline, or at all.
Acts 3:14-19 (KJV):
"...19 Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord."
He is speaking specifically to Israel here and telling them they "denied" and "killed" their Messiah. They must repent therefore (because they did this) and be converted (believe on their Messiah) that their sins may be blotted out WHEN THE TIMES OF REFRESHING SHALL COME (they had not come yet). Israel is being giving another chance here, even after rejecting and giving up their Messiah for crucifixion, to repent and accept him as their Messiah, by which then the Gospel of the Kingdom (Jesus spoke of when walking on the earth) would have been put into full effect and they would have had to endure in this faith into the Millennial Kingdom, where the times of refreshing shall come in the presence of the Lord.
Acts is a transitional book, and what then happened was Israel as a nation rejected their Messiah a final time with the stoning of Stephen in the chapters following this one, which caused them to be scattered in Acts 8. God then called and trained Paul and revealed the mysteries to him that were kept hidden from prophecy prior (mystery vs. prophecy: can be studied in Mid-Acts Dispensationalism, though I do not agree Paul was the first person in the body nor with hyper-dividing entire books away from Paul). These mysteries included the mystery Gospel of Grace (the "what" Jesus did: pay for sins on the cross: the mystery Gospel of Grace, Rom. 16:25, vs. the previous "who" Jesus was for Israel: "Jesus is your Messiah, you just messed it up Israel, repent and be converted to endure in your faith in him into the refreshing Millennial Kingdom": the Gospel of the Kingdom).
Also around this time we see God calling and saving the first Gentiles in Acts as the transition from Israel's scattering and temporary blinding (Rom. 11) begins and the move to provide the Gospel of Grace to the entire Gentile world "through their fall" (Rom. 11) begins, with mystery instructions for this parenthetical Church Age (DISPENSATIONALISM) being revealed to Paul, the Apostle of the Gentiles, who magnifies his office to them. During this Church Age, we are not under the New Covenant as Covenant Theologians would like to believe. That has been put on hold. The New Covenant will be instituted in the Millennial Kingdom (read Hebrews 8)...
This is why you guys really need to study Dispensationalism. It is way deeper and more accurate to scripture than covenant theologians who are like "Old Covenant, New Covenant, that's it. Unity. Sameness. Yay." It's not that simple. The mysteries must be divided from prophecy, and I'm not going to explain why, go back and read or do a keyword search in the KJV in all the Pauline Epistles for passages on the mysteries and read them in context.
I do believe I've provided plenty of info in here and I'm not obligated to give you doctrinal lessons on anything when I had to pray and study to find these things in my own time, and so should you. I did feel some conviction to show some proper respect to Ruckman, who even though I don't entirely agree with, and certainly never "idolized" or "worshipped" the guy, the man was nevertheless a genius and knew scripture better than all of these Covenant Theologians, and a certain aspect of his legacy deserves to be heard in its proper context when attacked for being in hell by someone who doesn't even know the difference between the Gospel of Grace and the Gospel of the Kingdom.
