It has always been by faith in God establishing and keeping His Promises:
Hebrews 11: NASB
1Now faith is the assurance of
things hoped for, the conviction of things not seen.
2For by it the men of old gained approval.
3By faith we understand that the worlds were prepared by the word of God, so that what is seen was not made out of things which are visible.
4By faith Abel offered to God a better sacrifice than Cain, through which he obtained the testimony that he was righteous, God testifying about his gifts, and through faith, though he is dead, he still speaks.
5By faith Enoch was taken up so that he would not see death; AND HE WAS NOT FOUND BECAUSE GOD TOOK HIM UP; for he obtained the witness that before his being taken up he was pleasing to God.
6And 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 seek Him.
7By faith Noah, being warned
by God about things not yet seen, in reverence prepared an ark for the salvation of his household, by which he condemned the world, and became an heir of the righteousness which is according to faith.
8By faith Abraham, when he was called, obeyed by going out to a place which he was to receive for an inheritance; and he went out, not knowing where he was going.
9By faith he lived as an alien in the land of promise, as in a foreign
land, dwelling in tents with Isaac and Jacob, fellow heirs of the same promise;
10for he was looking for the city which has foundations, whose architect and builder is God.
11By faith even Sarah herself received ability to conceive, even beyond the proper time of life, since she considered Him faithful who had promised.
12Therefore there was born even of one man, and him as good as dead at that,
as many descendants AS THE STARS OF HEAVEN IN NUMBER, AND INNUMERABLE AS THE SAND WHICH IS BY THE SEASHORE.
13All these died in faith, without receiving the promises, but having seen them and having welcomed them from a distance, and having confessed that they were strangers and exiles on the earth.
14For those who say such things make it clear that they are seeking a country of their own.
15And indeed if they had been thinking of that
country from which they went out, they would have had opportunity to return.
16But as it is, they desire a better
country, that is, a heavenly one. Therefore God is not ashamed to be called their God; for He has prepared a city for them.
17By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was offering up his only begotten
son; 18it was he to whom it was said, “IN ISAAC YOUR DESCENDANTS SHALL BE CALLED.”
19He considered that God is able to raise
people even from the dead, from which he also received him back as a type.
20By faith Isaac blessed Jacob and Esau, even regarding things to come.
21By faith Jacob, as he was dying, blessed each of the sons of Joseph, and worshiped,
leaning on the top of his staff.
22By faith Joseph, when he was dying, made mention of the exodus of the sons of Israel, and gave orders concerning his bones.
23By faith Moses, when he was born, was hidden for three months by his parents, because they saw he was a beautiful child; and they were not afraid of the king’s edict.
24By faith Moses, when he had grown up, refused to be called the son of Pharaoh’s daughter,
25choosing rather to endure ill-treatment with the people of God than to enjoy the passing pleasures of sin,
26considering the reproach of Christ greater riches than the treasures of Egypt; for he was looking to the reward.
27By faith he left Egypt, not fearing the wrath of the king; for he endured, as seeing Him who is unseen.
28By faith he kept the Passover and the sprinkling of the blood, so that he who destroyed the firstborn would not touch them.
29By faith they passed through the Red Sea as though
they were passing through dry land; and the Egyptians, when they attempted it, were drowned.
30By faith the walls of Jericho fell down after they had been encircled for seven days.
31By faith Rahab the harlot did not perish along with those who were disobedient, after she had welcomed the spies in peace.
32And what more shall I say? For time will fail me if I tell of Gideon, Barak, Samson, Jephthah, of David and Samuel and the prophets,
33who by faith conquered kingdoms, performed
acts ofrighteousness, obtained promises, shut the mouths of lions,
34quenched the power of fire, escaped the edge of the sword, from weakness were made strong, became mighty in war, put foreign armies to flight.
35Women received
back their dead by resurrection; and others were tortured, not accepting their release, so that they might obtain a better resurrection;
36and others experienced mockings and scourgings, yes, also chains and imprisonment.
37They were stoned, they were sawn in two, they were tempted, they were put to death with the sword; they went about in sheepskins, in goatskins, being destitute, afflicted, ill-treated
38(
men of whom the world was not worthy), wandering in deserts and mountains and caves and holes in the ground.
39And all these, having gained approval through their faith, did not receive what was promised,
40because God had provided something better for us, so that apart from us they would not be made perfect.
