AD70 was not the Second Coming. AD70 was only the outward show of the parousia of Christ. It was a "SIGN" of the Son of Man in heaven. The number of times words such "manifesting," "appearing," "revelation," and the like point out that what was revealed in time was already a spiritual reality in the eternal realm. This is akin to Christ declaring, "thy kingdom come on earth, as it is in heaven."
As witnessed in John 14:17-24, the Lord comes to abide within His people. He doesn't come to the world at large. This is the intent of Christ's declaration to the heart hearted "true believers" of Temple leadership, "you will not see me again until you say 'blessed is he who comes in the name of the Lord.'" The kingdom does not come with visible observation, despite the teaching regarding the fall of Jerusalem being the proof that the kingdom had arrived.
Though it may be tempting to think that the appearing of Christ and His Kingdom was world-wide in some external sense, this is not the case. The glory of the Lord specifically dwells within His temple - which is the "body of Christ" or "bride." There are a number of verses which point out that the Spirit and Kingdom dwells within.. not just 'around' (except insofar as the people of the kingdom are around). Therefore, the world at large cannot see Him or know Him or have any part of His kingdom until such time as they say "blessed is he who comes in the name of the Lord." There are numerous passages which intimate this idea, but here are just a few:
Luke 17:21 nor will they say, 'See here!' or 'See there!' For indeed, the kingdom of God is within you."
John 14:17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
John 14: 22-23 Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world? Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.
Romans 8:9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
2 Corinthians 6:16 And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.
Ephesians 3:17 That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love,
1 John 4:13 Hereby know we that we dwell in him, and he in us, because he hath given us of his Spirit.
Galatians 4:6 Because you are sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, "Abba, Father."
