Yes the kingdom and the gospel of the kingdom was first preached by John the Baptist, the forerunner of Christ which is the Son of God and King that Israel was to accept and believe on. "Whosoever" believed on Christ and His gospel of the kingdom could be saved (the NT talks about proselytes into Judaism). Who disagrees with that? Yes, grace and truth came with Jesus Christ. He died four sins and through His blood we have redemption (Col. 1:14, Eph. 1:7), what else is new?
I do not know what that means, but I do know that Jesus's church (which is apparently the called out assembly of the little flock that believed the kingdom gospel) started with John the baptist. The body of Christ, which is also a church, started with Paul in Acts 9. The spiritual organization the, body of Christ, can only exist BY THE CROSS so anytime pre-cross is unacceptable. (Eph. 2:16)
That is completely made up in the mind of Herb Evans. The King, His kingdom, and His kingdom gospel were offered starting with John the Baptist. None of that is going on today. The new dispensation is clearly something given through Paul. (1 Tim. 1:10-17, Eph. 3:1-7, 1 Cor. 9:17, Col. 1:25)
Ephesians 2:16 " And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby:"
I have already refuted this in Part 2. Yes Christ was the last sacrifice needed--no more bulls and goats. Anyone could believe on the King and therefore do His works (John 14:12) and become a proselyte to Judaism and have part in the kingdom.
I will point out that Herb Evans used a verse out of Acts 10 to prove that whosoever believeth on Christ could get saved (which includes doing His works as I showed you already in part 1 with John 14:12). But Peter and his friends were shocked when the Gentiles got saved without water baptism.
 To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.
 While Peter yet spake these words, the Holy Ghost fell on all them which heard the word.
 And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost.
 For they heard them speak with tongues, and magnify God. Then answered Peter,
 Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we?
 And he commanded them to be baptized in the name of the Lord. Then prayed they him to tarry certain days.
Peter was commissioned by Jesus to preach water baptism as part of the gospel in Matthew 28:17, Mark 16:15-16, and Acts 2:38. But when Israel blasphemed the Holy Ghost in Acts 7 with the stoning of Stephen, God transitioned things from prophecy to mystery and Israel to body of Christ. You can read the first part of Acts 10 and see that God was letting Peter know that there had been a change in the dietary laws and then at the end of the chapter God let Peter know that works were no longer required. To understand the transitional period of Acts one must study Romans 9-11.
That is all a bunch of unscriptural babbling built on the assumption that every church in the Bible is the body of Christ and that every "gospel" is the same. A "church" is a called out assembly and God has had many starting from the OT (Acts 7:38). I have already gone over these things in part 1.
 That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world:
 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.
 For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us;
 Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace;
 And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby:
 Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)  And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:
 And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;
 God forbid. How shall we, that are dead to sin, live any longer therein?
 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
 For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
 Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
 For he that is dead is freed from sin.
 Now if we be dead with Christ, we believe that we shall also live with him:
 Knowing that Christ being raised from the dead dieth no more; death hath no more dominion over him.
 For in that he died, he died unto sin once: but in that he liveth, he liveth unto God.
 Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
