Presenting this again,
John 14:6
If Jesus is the only way to the father, then how did the O.T. persons know God?
How do you reconcile this?
This question is mostly directed at those considering themselves biblical adherents,
I wish you had phrased it a little differently. Are you thinking of Jews, or all people before Christ?
If you read the book of Job, and even Paul, you will find your answer.
Job told us that he was looking forward to his redeemer!
Job 19:25: And as for me, I know that my Redeemer liveth, and the Last, he shall stand upon the earth;
Paul told us also that the Mosaic Law was a tutor leading to Christ!
Galatians 3:24: So that the law has been our tutor up to Christ, that we might be justified on the principle of faith.
The way it was a tutor is somewhat easy to explain if you were a Jew. The thing is that the Law (of
Moses) promised all to live not by faith, but by works. If they obeyed the Law perfectly, they would never die; on the other hand, if they disobeyed even a little, they would die, for 'the sinner shall die.'
This is how they all came to realize that by works of Law (
M), none would survive, and all would be condemned to eternal death. Thus, they all remembered the Passover Lamb that had the angel of death pass over that house and forgive the ones in that house (the firstborn). They realized that the Messiah promised would come and redeem them. Thus all of them looked forward to Christ, they all (mostly) believed in him. So, even Noah, Abraham, and all the others before Christ believed in his redemption of them - to come.
All non Jews that never knew God shall be judged by Christ according to their own consciences on the day of judgment:
Rom 3:
14 For when those of the nations, which have no law, practise by nature the things of the law, these,
having no law, are a law to themselves; 15 who shew
the work of the law written in their hearts, their conscience also bearing witness, and
their thoughts accusing or else excusing themselves between themselves 16 in the day when God shall judge the secrets of men, according to my glad tidings, by Jesus Christ.
So, everybody shall be judged by Christ. Some will have to be resurrected (the unrighteous) and then be taught about Christ, about God. If they accept the faith, they get to live and be tested when satan is let out of prison.
