Salvation is all to the glory of God, for the glory of God. God chooses whom he wills without asking your opinion. It's called Sovereignty.

Mat 15:23-28
But He answered her not a word.
And His disciples came and besought Him, saying,
Send her away; for she is crying after us.
But He answered and said,
"I am not sent but unto the lost sheep of the House of Israel."
Then came she and worshipped Him,
Saying, "Lord, help me."
But He answered and said,
"It is not meet to take the children's bread,
and to cast it to dogs."
And she said,
"Truth, Lord:
Yet the dogs eat of the crumbs which fall from their masters' table."
Then Jesus answered and said unto her,
"O woman, great is thy faith:
be it unto thee even as thou wilt."
And her daughter was made whole
from that very hour.
Thank-you...
