Jesus Christ's Parents was both Jewish from the house of David and Abraham.
He read the Torah in Temple and spoke with the Rabbi's even celebrated passover.
Matthew 5:17 KJV says: Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill.
But in my opinion Christianity vaguely has anything to do with Heaven just mostly Sheol or Hell.
People who obey the law and try not to sin goes to Heaven people who do not go to Hell.
