Entrance into Heaven has ALWAYS been via worship of the Triune God....and is open to ALL who have done so over the course of history.
This is proven-out in Revelation is the construction of the New Jerusalem....i.e....Tribes of Israel....disciples....THREE entrances on each of four directions....built as a cube (THREE dimensions).
So...the ancient Hebrew (Jews) remnant that worshipped God as Triune will make it to Heaven.
Jews that deny the Triune creator will be judged for such, and never make it to Heaven.

My understanding of what is the Narrow Gate is based on what the BIBLE actually SAYS:
John 1:12-13 (RSV)
[SUP]
12 [/SUP] But
to all who received him, who believed in his name,
he gave power to become children of God;
[SUP]
13 [/SUP] who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.
Colossians 2:6 (NIV)
[SUP]
6 [/SUP] So then, just as
you received Christ Jesus as Lord, continue to live in Him,
Romans 10:9 (NASB)
[SUP]
9 [/SUP] that if you
confess {not just profess} with your mouth
Jesus as Lord{which means to willingly submit to HIM as Master}, and believe in your heart that God raised Him from the dead, you will be saved;
1 John 2:4 (NASB)
[SUP]
4 [/SUP] The one who says,
"I have come to know Him," and does not keep His commandments,
is a liar, and the truth is not in him;
Malachi 3:6 (NKJV)
[SUP]
6 [/SUP] "For
I am the LORD,
I do not change;
Therefore you are not consumed, O sons of Jacob.
Romans 4:3 (HCSB)
[SUP]
3 [/SUP] For what does the Scripture say?
Abraham believed God, and it was credited to him for righteousness.
O.T. Saints believed GOD, trusting HIM totally that Messiah the LORD would come.
N.T. Saints believed GOD, trusting HIM totally that Messiah the LORD did come.
Both are part of
the Bride of CHRIST.
Jeremiah 2:2-3 (NIV)
[SUP]
2 [/SUP] "Go and proclaim in the hearing of Jerusalem: "'I remember the devotion of your youth,
how as a bride you loved me and followed me through the desert, through a land not sown.
[SUP]
3 [/SUP]
Israel was holy to the LORD, the firstfruits of his harvest; all who devoured her were held guilty, and disaster overtook them,'" declares the LORD.
Isaiah 62:5 (HCSB)
[SUP]
5 [/SUP] For as a young man marries a young woman,
so your sons will marry you; and
as a groom rejoices over ⌊his⌋ bride,
so your God will rejoice over you.
Ephesians 5:25 (YLT)
[SUP]
25 [/SUP] The husbands! love your own wives, as also the
Christ did love the assembly, and did give himself for it,
Colossians 1:18 (HCSB)
[SUP]
18 [/SUP]
He is also the head of the body, the church; He is the beginning, the firstborn from the dead, so that He might come to have first place in everything.
