This is correct. Believers are called by the Father, through the Spirit, and given to the Son. This has always been the sovereign decree of God. Our Particular Baptist forefathers understood this:
1.5._____ Those of mankind that are predestinated to life, God, before the foundation of the world was laid, according to his eternal and immutable purpose, and the secret counsel and good pleasure of his will, hath chosen in Christ unto everlasting glory, out of his mere free grace and love, without any other thing in the creature as a condition or cause moving him thereunto.
(
Ephesians 1:4, 9, 11; Romans 8:30; 2 Timothy 1:9; 1 Thessalonians 5:9; Romans 9:13, 16; Ephesians 2:5, 12 )
All believers are predestined in Christ before the foundation of the world (Ephesians 1:3-4). That is what the text says. It is unambiguous and clear as a bell. Believers throughout out all of human history, have been chosen from the beginning (from eternity) for salvation in Jesus Christ (2 Thessalonians 2:13-14). To suggest that Calvinists believe otherwise is not a simple misunderstanding of Calvinism, it is a blatant falsehood. That is why certain individuals will not receive a direct response from me.
