Ye serpents, ye generation of vipers, how can ye escape the damnation of hell?
Wherefore, behold, I send unto you prophets, and wise men, and scribes: and some of them ye shall kill and crucify; and some of them shall ye scourge in your synagogues, and persecute them from city to city: That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel unto the blood of Zacharias son of Barachias, whom ye slew between the temple and the altar. Verily I say unto you, All these things shall come upon this generation. O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not! Behold, your house is left unto you desolate. For I say unto you, Ye shall not see me henceforth, till ye shall say, Blessed is he that cometh in the name of the Lord.
Matthew 27:25 Then answered all the people, and said, His blood be on us, and on our children.
Romans 11:25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
II Peter 3:8 But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day
Psalm 90:4 For a thousand years in thy sight are but as yesterday when it is past, and as a watch in the night.
Hosea 6:1-2 Come, and let us return unto the LORD: for he hath torn, and he will heal us; he hath smitten, and he will bind us up. After two days will he revive us: in the third day he will raise us up, and we shall live in his sight
Luke 13:32 And he said unto them, Go ye, and tell that fox, Behold, I cast out devils, and I do cures to day and to morrow, and the third day I shall be perfected.
Exodus 19:14-20 And Moses went down from the mount unto the people, and sanctified the people; and they washed their clothes. And he said unto the people, Be ready against the third day: come not at your wives. And it came to pass on the third day in the morning, that there were thunders and lightnings, and a thick cloud upon the mount, and the voice of the trumpet exceeding loud; so that all the people that was in the camp trembled. And Moses brought forth the people out of the camp to meet with God; and they stood at the nether part of the mount. And mount Sinai was altogether on a smoke, because the LORD descended upon it in fire: and the smoke thereof ascended as the smoke of a furnace, and the whole mount quaked greatly. And when the voice of the trumpet sounded long, and waxed louder and louder, Moses spake, and God answered him by a voice. And the LORD came down upon mount Sinai, on the top of the mount: and the LORD called Moses up to the top of the mount; and Moses went up.
And it goes on and on, but bottom line is when was the end of the Jewish dispensation and when was the beginning of the church? Did it involve the rejection of a generation and the receiving of another? And how does it all line up with the other dispensations?
Start and end can be surmised by other possible time lines that I did not list, so here goes.
Becoming of age (recognized manhood)
Jesus being baptized
Pentecost and the giving of the Holy Spirit
The answer is found in the Word, and the signs of the times will testify our nearness to the next great event. Lets watch and be ready! Not trying to be cryptic, just showing some scriptures that imply something very important.
