I agree with you, in the church age discourse...Prior to the Crucifixion, Jesus was preaching to and teaching Jews...They were all under the Law...Including Jesus...None of them went to heaven when they died...They all went to Paradise...
Rom 2:13 For not the hearers of the law are just before God, but the doers of the law shall be justified.
It's difficult to deny this verse and the many that support it...During the time period of the course taken by the book of Acts, it is clear (to me) that a (slow) transition was taking place...
Rom 2:25 For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
Rom 2:27 And shall not uncircumcision which is by nature, if it fulfil the law, judge thee, who by the letter and circumcision dost transgress the law?
Being subject to the Law was extremely important during the ministry of Jesus...
Rom 3:28 Therefore we conclude that a man is justified by faith without the deeds of the law.
AGAIN...
Rom 2:13 For not the hearers of the law are just before God, but the doers of the law shall be justified.
Rom 3:28 Therefore we conclude that a man is justified by faith without the deeds of the law.
I don't know how one can deny that those during Jesus' ministry and during the beginning of the book of Acts and Romans were under the Law...
No one denies they were under the law. However, it was not following the law that saved them. Just as with Abraham it was the FAITH that caused them to follow the law that saved them.
