One place that we can find the answer is in Matthew 13:44.
"Again, the kingdom of heaven is like treasure hidden in a
field, which a man found and hid; and for joy over it he goes and
sells all that he has and buys that field."
First let us remember who Jesus Christ came to redeem. In Matthew 15:24
Christ said:
"But He answered and said, I was not sent except to
the lost sheep of the house of Israel."
Looking back at Matthew 13:44, Christ came to earth and found his
lost sheep hidden in the world. Then he re-hid them.
Their identity is not widely known even today. Christ gave all
that he had, his life, to purchase the field, the world.
Matthew 13:38 "The field is the world,"
This is how we know that the field is the world. The Bible many
times tells us how to "decode" what is hidden or seems
hidden.
So Christ redeemed his lost sheep (redeemed Israel) and also
made it possible for salvation to be offered to the entire field
or the whole world through his purchase of the world.
So the answer is yes. All who God draws to him can be saved
whoever they are in the whole world. Now who did God give the job
of taking the gospel to the whole world? He gave the job to his
sheep, the remnant of the house of Israel. Many people
have been confused as to who these people are in the world today.
We now have proof who these people really are physically. They
are the same people who most people attribute the job to
spiritually. If you are a descendant of the Anglo-Saxon,
Germanic, Scandinavian and kindred peoples then you are more than probably a
physical descendant of the Biblical Israelites. Who in the world
today is sending most of the missionaries to the world? Who in
the world today is distributing most of the Bibles to the world?
Who in the world today cares enough to send relief and supplies
to the suffering of the world? Keep up the good work fellow
Israelites, you are indeed God's chosen people!
