The Jews did not have any idea of inheriting a paradise in heaven. Biblical and secular history proves that the Jews up to Christ's time looked to a restored earthly paradise. So when the Jews questioned him about how to “inherit everlasting life,” they were also confirming that the promises found in Psalms were of a literal earth (Mt 19:16; Lk 10:25-27).
No, the Jews did not have any idea of going to heaven at all. However, when Christ came, things changed.
“The Law and the Prophets were until John. From then on, the Kingdom of God is being declared as good news, and every sort of person is pressing forward toward it. 17 Indeed, it is easier for heaven and earth to pass away than for one stroke of a letter of the Law to go unfulfilled. - Luke 16:16, 17
Christ offered the hope of heavenly life, and his apostles echoed it. (John 14:1-4; 2 Cor 5:1,2; Phil 3:13-21; Col 1:3-5; 1 Pet 1:4)
Christians did not have the hope of paradise earth. Consider this: if they did, wouldn't at least ONE of them have spoken about it? But not a single one did. There isn't a single expression from Peter, Paul, James or John about a paradise earth. Of course, a paradise earth WOULD be good news, wouldn't it? If that were the case, then why did Paul say what he said at Gal 1:6-8? Especially verses 8 and 9. Even an ANGEL would be cursed if a DIFFERENT good news were declared. Something serious to think about.
In addition, Ephesians 4:4 talks about "the one hope", not "two distinct hopes". (w13 12/15 p. 25 par. 13)
The only way around the passages above is to say that the Greek Scriptures were written primarily for the anointed. (w08 1/15 p. 22 par. 11) That is a whole other discussion, and has all the markings of 'shutting up the Kingdom of the heavens.' (Matt 23:13)
