I believe any human ever born can be saved based upon faith in Christ . But in the ot they had to wait in rest for fulfillment of the promises of messiah the savior and lord
we’ve been born when God tells a man who believes and is about to die this
“And Jesus said unto him,
Verily I say unto thee, To day shalt thou be with me in paradise.”
Luke 23:43 KJV
But in the ot when they were going to die this was the message
“And the LORD said unto Moses,
Behold, thou shalt sleep with thy fathers; and this people will rise up, and go a whoring after the gods of the strangers of the land, whither they go to be among them, and will forsake me, and break my covenant which I have made with them.”
Deuteronomy 31:16 KJV
which meant this was about to happen
“So
Moses the servant of the LORD died there in the land of Moab, according to the word of the LORD.
And he buried him in a valley in the land of Moab, over against Beth-peor: but no man knoweth of his sepulchre unto this day.”
Deuteronomy 34:5-6 KJV
But to Christian’s they are told
“Jesus said unto her, I am the resurrection, and the life: he that believeth in me,
though he were dead, yet shall he live: and whosoever liveth and
believeth in me shall never die. Believest thou this?”
John 11:25-26
“Verily, verily, I say unto you,
If a man keep my saying, he shall never see death.”
John 8:51 KJV
It’s become about Christian’s parting from thier body when it dies and going to Jesus alive by the spirit of which they are reborn and given life
“Therefore we are always confident, knowing that,
whilst we are at home in the body, we are absent from the Lord:
(for we walk
by faith, not by sight
we are
confident, I say, and willing rather
to be absent from the body, and to be present with the Lord. Wherefore we labour, that, whether present or absent, we may be accepted of him. For we must all appear before the judgment seat of Christ; that every one may
receive the things done in his body, according to that he hath done, whether it be good or bad.”
2 Corinthians 5:6-10 KJV
They were waiting for jesus to be born and accomplish the gospel we aren’t we have promises of life and not death because of jesus but indeed Abraham Isaac and Jacob we are hiers of the same kingdom same life after death
“And I say unto you, That
many shall come from the east and west, and shall
sit down with Abraham, and Isaac, and Jacob, in the kingdom of heaven.”
?Matthew 8:11 KJV
It’s just that there was no life for man until Jesus gave his for us the promise was always there and wherever God made the promise the. Faith is available for the Hearer who believes him
