God accomplishes all his will, and none can stay his hand, Dan 4:35. If God wanted all mankind to live in heaven, he would have had Jesus to die for all mankind, but he did not because Jesus died only for those that God gave him and all that he died for will live in heaven, without the loss of even one. God could have had Jesus die for all mankind, but he did not.
Absolutely not true, Forest.
1 John 2:
2) And he is the propitiation for our sins: and not for ours only, but also for
the sins of the whole world.
1 Tim 2:
4) Who will have all men to be saved, and to come unto the knowledge of the truth.
2 Pet 3:
9) 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.
John 3:
16) For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
17) For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
As I said before, you maintain a death grip on your misunderstanding of 1 Cor 2:14.
The Calvinism you have embraced is a false doctrine.
