Faith is a gift of the Holy Spirit... it is by His power and your obedience to it. Do you have it in the first place? Or is it the gift of God? Eph. 2:8. In the gospel books... we find John filled with the Holy Spirit from his mother's womb. Luke 1:15. He began the Kingdom with the Kingdom gospel "good news" message... repent and be baptized and your sins will be forgiven. Now John being filled with the Holy Spirit had faith and power to draw... but was not given power to do miracles. So the people that came to him and heard his message and drew upon his faith, their sins were indeed forgiven. Mark 1:4.
Christ was filled also with the Holy Spirit, we can read this in Luke 4:1. Christ was completely filled up with the power and faith of the Spirit. He did miracles... and anyone who believed His message, the "good news" He preached could draw upon His faith and receive healings, etc., etc.. It is like being inside a house with curtains closed on every window or being outside a house. Inside the house you may know the sun is shining, but it is not until you go outside and stand under the sun do you feel its warmth. You can believe it is warm all you want, but not until you go outside and activate that belief will you be warm by it. Christ was the Son/Sun, He stood outside every day. Multitudes listen but stood afar off as though they were in a house with closed curtains. The apostles were under Him, basting in His Love and Warmth and holding on to every word, as though He were the Sun. Christ was in the world . . . the Kingdom of God was upon the House of Israel.
You will find more Gentiles drawn to Him and saved than the House of Israel. Christ, in John's Chapter 6, was feeding them the bread of life if they would listen. But they wanted manna from heaven that which they could eat and be filled. Christ said you will be filled and satisfied and be raised in the last day if you eat of Him.... meaning draw from Him... His faith and believe. Aside from Him they could not have faith... for again this was a gift of the Spirit. And no one could have this faith that were not drawing off His faith, because the Spirit was not promised to come until after His death and resurrection and ascension. John 14:16, Acts 1:4. If they could not believe Him while they saw Him, and saw what He did as far as signs and miracles and wonders . . . then how could they believe what they could not see? The house of Israel was empty in belief and empty in faith; even the old time faith of faithfulness like their father Abraham. They were deaf and they did not have sight. He showed examples by miracles how to see and how to hear, but they did not believe.
"The Kingdom Gospel" message was drawing the House of Israel to Him. John 1:33. Christ told the apostles do not go to anyone except the House of Israel... the lost sheep. Matt. 10:5-7, 15:24. During the preaching of the Kingdom gospel was to draw the sheep to the Shepherd, but they did not hear His voice. If they would of heard His voice, then the Kingdom of God would of been established on earth, but that did not happen.
Salvation through faith in Christ's death and resurrection could not be revealed until after His death and resurrection. Satan has been on the prowl since the Garden, trying to snuff out every seed that would come forth to be King . . . bringing forth the Kingdom of God. Prophecy clearly preached there would be a King, so Satan's main task was to kill the King. Then the earthly kingdoms were his. And this is exactly what Satan did. If anyone would of known differently, then Satan would have also known... and Christ would not have been the sacrificial lamb to lift the curse off of all man-kind. 1Cor. 2:6-8. Satan's task of killing one is not a great feat, but to kill all the world after Christ's saving grace is upon us... is surely a greater task.
None of the "mystery" revealings nor "revelations given Paul or John or even Peter... were made known to them, until after the death and resurrection and ascension of Christ. Acts 26:16-18 (16). God's plan to lift the curse from the world, according to prophecy, needed to take place with Satan following through with his part.
The Pharoah in Exodus was used to move the children of Israel. Satan was working though the chief priests, Judas and even Peter, infecting the crowds that stood on that day, as they demanded Christ be crucified. Everything went according to God's plan in order to achieve the exact order of things to take place, so that not only the house of Israel would be saved, and also the Gentiles. For God's ultimate plan was to draw all to Him. Even if all were not drawn to Him for eternal life, they would all be drawn to Him and raised on the last day to receive their just reward (John 6:40) which will be either everlasting eternal life or everlasting condemnation in fire and brimstone. Rev. 20:11-15.
God is good and loving and patient. He, through His Son, lifted all Israel to Him by means of the resurrection of their own bodies, whether they be physically dead or physically alive, to be raised on the last day. This is all about the Kingdom Gospel message and what it offered...
Once the curse was lifted, then the gathering began; first to the House of Israel, who rejected it three times. If Israel would have accepted it, they would have entered into their rest, but again, they did not accept it. The promised Kingdom was put on hold due to the third rejection... which was once by God (John 1:6,33, Mark 1:4, etc.) once by the Son (Matt. 4:17) and once by the Holy Spirit (Acts 2:38). Three strikes and now it is a new ball game. Who are we to question God. He has a master plan to bring every single one of us before Him.
After the third rejection of the Kingdom Gospel, a new revelation was given to Paul and He was sent to bring this message to the Gentiles (Gal. 1:11,12), and more revelations were given. Eph. 3:1-11, Rom. 16:25. The book of Revelation was later given to John. Peter received visions.. Paul was separated by God's Spirit (Acts 13:2),but this was not of his own doing, or Paul's plan, but this was God's plan. The Kingdom message was the gathering of the House of Israel. Now we have a grace message and a different gospel which is the gathering of "the body of Christ". Eph. 1:13,14, 1Cor. 12:13, Eph. 5:31+32. The message went to the Jews first (Acts 13:16-43) and to the Gentiles. The body is the body of Christ; no distinction between Jew or Gentile; this house or that house. We are baptized into this body by one Spirit, the Holy Spirit. 1Cor. 12:13. We enter this body through faith which is a gift of this same Spirit. Eph. 2:8, 1:13,14. We believe the "gospel" of the gathering of "the body of Christ" and we enter in... Eph. 2:8-13.
It is by the Kingdom gospel, one enters the Kingdom. It is by the Grace Gospel we enter into "the body of Christ." One can not enter the prophesied earthly Kingdom today, because there is no King. And there will not be no King until the Lord comes as King of Kings and Lord of Lords, and rules over a Kingdom and all this is under Him, as He is in His heavenly Kingdom, with the "body". The body is where the Head is, in Heaven. Eph. 2:4-7, Col. 3:1-4. The body and the head are one unit. The church is not under Him, in the heavenly. We are one with Him.
The Kingdom gospel will not come again... nor will the Kingdom be set up again until "the body of Christ" is gathered. There has to be a completion a full circle of events that need to take place... right now, in the flesh, it is like saying the head is severed from the body. When the two unite, then it is indeed "One" body. 1Thes. 4:17. And with Him we will rule over the Kingdom from the heavenly abode. We will not be limited to walk just in the heavens, or limited to walk only through the newly established kingdom on earth. We will judge men and angels so Scripture says. 1Cor. 6:2,3. We are now being gathered through the new gospel message into "the body of Christ". If this is so hard to believe, then where is your faith? We have more today than the house of Israel had 2000 years ago. We each have access to the Spirit and to His gifts and divine faith. Eph. 2:8. The house of Israel had Christ alive with them, but they did not see Him... they did not hear Him... they could not draw their saving grace from Him. They did not believe what they could see. Rom. 3:21-26.
 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
