Q. Why does the bible say that Jesus came to save the world and not condemn it but also Jesus says He didn’t come to bring peace but a sword turning son against father, etc?
A. In John 1:29 John the Baptist called Jesus “the Lamb of God who takes away the sin of the world.” but although He died for the whole world, only those who believe in him can have their sins forgiven (John 3:16).
The reason He said He didn’t come to bring peace but a sword is because He knew there would be contention between those who believe in Him and those who don’t. This has caused families to be divided, and has even been the reason wars have begun. So it wasn’t that He promoted this division between people but that He knew it would happen because of him.
