I will let the writer of the Book of Hebrews answer your question about how God dealt with men in the past.
Heb_11:4 By faith Abel offered to God a more excellent sacrifice than Cain, through which he obtained witness that he was righteous, God testifying of his gifts; and through it he being dead still speaks.
Heb_11:5 By faith Enoch was taken away so that he did not see death, "AND WAS NOT FOUND, BECAUSE GOD HAD TAKEN HIM"; for before he was taken he had this testimony, that he pleased God.
Heb_11:6 But without faith
it is impossible to please
Him, for he who comes to God must believe that He is, and
that He is a rewarder of those who diligently seek Him.
Heb_11:7 By faith Noah, being divinely warned of things not yet seen, moved with godly fear, prepared an ark for the saving of his household, by which he condemned the world and became heir of the righteousness which is according to faith.
Heb_11:8 By faith Abraham obeyed when he was called to go out to the place which he would receive as an inheritance. And he went out, not knowing where he was going.
Heb_11:9 By faith he dwelt in the land of promise as
in a foreign country, dwelling in tents with Isaac and Jacob, the heirs with him of the same promise;
Heb_11:11 By faith Sarah herself also received strength to conceive seed, and she bore a child when she was past the age, because she judged Him faithful who had promised.
Heb_11:13 These all died in faith,
not having received the promises, but having seen them afar off were assured of them, embraced
them and confessed that they were strangers and pilgrims on the earth.
Heb_11:17 By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises offered up his only begotten
son,
Heb_11:20 By faith Isaac blessed Jacob and Esau concerning things to come.
Heb_11:21 By faith Jacob, when he was dying, blessed each of the sons of Joseph, and worshiped,
leaning on the top of his staff.
Heb_11:22 By
faith Joseph, when he was dying, made mention of the departure of the children of Israel, and gave instructions concerning his bones.
Heb_11:23 By faith Moses, when he was born, was hidden three months by his parents, because they saw
he was a beautiful child; and they were not afraid of the king's command.
Heb_11:24 By faith Moses, when he became of age, refused to be called the son of Pharaoh's daughter,
Heb_11:27 By faith he forsook Egypt, not fearing the wrath of the king; for he endured as seeing Him who is invisible.
Heb_11:28 By faith he kept the Passover and the sprinkling of blood, lest he who destroyed the firstborn should touch them.
Heb_11:29 By faith they passed through the Red Sea as by dry
land, whereas the Egyptians, attempting
to do so, were drowned.
Heb_11:30 By faith the walls of Jericho fell down after they were encircled for seven days.
Heb_11:31 By faith the harlot Rahab did not perish with those who did not believe, when she had received the spies with peace.
Heb_11:33 who
through faith subdued kingdoms, worked righteousness, obtained promises, stopped the mouths of lions,
Heb_11:39 And all these, having obtained a good testimony through faith, did not receive the promise,
God has always dealt with men and women through faith.
We should all use the New Testament writers as our witnesses to interpreting the Old Testament, based on progressive revelation of scripture.
A person could go to the Old Testament and tell me I am forbidden from eating shrimp.
However, if we use the New Testament writers as our witnesses, we know that the New Covenant has made the Old Covenant "obsolete". (Hebrews 8:13)
Much of the confusion found in the modern Church is because the New Covenant has been buried under manmade traditions. There is a clear difference between the Old Covenant and the New Covenant of Christ. (Hebrews 12:18-24)
Sadly, the Judaisers have won the day during most of the last 2,000 years.
I have to wonder how many souls could have been saved if they had been presented with an understanding of the New Covenant, which makes the whole Bible a book about Jesus Christ?
John Darby's doctrine turns the New Covenant Church, made up of Israelites and Gentiles grafted together, into a "parenthesis" in God's Plan for the nation of Israel.
This takes the focus off of Christ and replaces it with a race of people and a piece of land.
It is a form of "Replacement Theology".
