Six days later Peter, James and John saw a fore-view of Christ in his kingdom glory at the transfiguration. We read in John 12:23, 31-32, “The hour is come, that the Son of man should be glorified. Now is the judgment of this world: now shall the prince of this world be cast out. And I, if I be lifted up from the earth, will draw all men unto Me.” This also describes the coming of the Son of man into His Kingdom, and speaks most gloriously of the triumph of Christ over Satan at His resurrection. It predicts that His death will begin this mighty spiritual Kingdom, that men will be drawn to Him, and that the power of Satan on the earth will be severely limited.
Jesus said in Luke 17:20-21, “The kingdom of God cometh not with observation: neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is among you.” After Christ's ascension the kingdom of God and of his Christ came with full power at Pentecost beginning the salvation age, Acts 2:17-21, until 1 Cor. 15:24-26.
That would only work if you apply Matt.16:27 to that of the day of pentecost.
