There is only one age that came to and end. Jesus said the harvest is the end of "this age". So all we need to figure out is What Age Did Jesus live in? In the first century AD, there was only two ages spoken about and Daniel predicted the only age to come to an End.

Luke 20:34-35 NASB 34 Jesus said to them, "The sons of THIS AGE marry and the women are given in marriage, 35 but those who are considered worthy to attain to THAT AGE and the resurrection from the dead, neither marry nor are given in marriage; (Caps mine)

Jesus identified the Age He was living in and the age about to come. The point is, "THAT AGE" is not Heaven. We Christians after the END came, live in "THAT AGE" but in the House of God (Body of Christ, His Spiritual Kingdom) We are married to Christ. We still marry in the physical world but not in the spiritual world.

Now the question is what Age was Jesus living in when He said "THIS AGE"?

Fact: Jesus lived in "THIS AGE" which came to an End when the Temple fell. That WAS THE OLD COVENANT AGE. Now we live in "THAT AGE" also known at the Church/Christian Age that never Ends.
