What is free will if He made them and knows all?
Salvation would have been impossible if it was not for God "
omniscience". Man is born spiritually dead because of Adam's sin which he brought upon himself, and all of his descendants. The only way a man could be found "
in Christ" is he had have been placed in him (Christ) before the world began!!! That requires God to have
"known before hand" what every man's decision would have been after hearing the Gospel message of his salvation. We find that truth here...
2Tim 1:9 Who
hath saved us, and called us with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus
before the world began,
My salvation nor anyone else, did not happen on specif date in history, it happened before the world began, because the Lord God knew before he created the earth, even before the first man was ever formed, what I would chose after I heard the Gospel.
Jesus came to the earth carrying his seed within himself which was his descendants, his Church. Man is saved in exactly the same way man became a sinner in Adam. This is why Jesus is known as the
"last Adam"
We died in the first Adam, we became alive in the last Adam. If there was no
"omniscience" on God's part then man would never have a choice whom he will serve, and salvation would have been impossible!!!
