Are you saying they couldn’t have FAITH before 70 A.D.? FAITH is Loyalty to The LORD.
[Galatians 3:23-26 NKJV] But before faith came, we were kept under guard by the law, kept for the faith which would afterward be revealed.
[24] Therefore the law was our tutor to bring us to Christ, that we might be justified by faith.
[25] But after faith has come, we are no longer under a tutor.
[26] For you are all sons of God through faith in Christ Jesus.
