Predestinated to Salvation !2
For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.
Now those He foreknew [His Elect] them He predestinated to be conformed to the image of His Son, hence they were predestinated to the Adoption of Sons Eph 1:4-5
4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will,
Now in being predestinated to the image of Christ, we must be conformed to Him in spiritual qualities and principles and the frame of our hearts! All of which means, we must be saved from the penalty and power of sin, and glorified.
All this has been predestinated from before the foundation, not to all mankind, but solely to Gods Chosen, Chosen in Christ before the foundation Eph 1:4-5.
So that's how we know that some men have been Chosen and Predestinated to Salvation!
