Rev 13:8
8 And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
9 If any man have an ear, let him hear.
In Preaching the Cross of Christ, we cant hold back the offensive Gospel Truth that Salvation is limited to them whose names were written in the book of life from the foundation of the world
God has already written the names of them He has purposed to save in the Lambs Book of Life from the foundation of the world,
Jesus said on one occasion Luke 10:21
Notwithstanding in this rejoice not, that the spirits are subject unto you; but rather rejoice, because your names are written in heaven.
Those are the only ones He was slain, crucified for, so that's an aspect of preaching the Cross.
Not if you believe scripture
1 Timothy 2:4–6

John 6:51
I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world.
2 Corinthians 5:14–15
14 For the love of Christ constraineth us; because we thus judge, that if one died for all, then were all dead: 15 And that he died for all, that they which live should not henceforth live unto themselves, but unto him which died for them, and rose again.
John 11:51
And this spake he not of himself: but being high priest that year, he prophesied that Jesus should die for that nation;

2 Corinthians 5:19
To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.

The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
Calvinists must imagine the Holy Spirit is an incompetent source. He just can't seem to communicate the Calvinists doctrine of limited atonement
