Ah, the warm love of the Calvinist god who creates the lost from the foundation of the world. John Calvin was a heretic who took grace to such an extreme that he made God himself the author of sin. Arminianism is the blue collar false gospel for the legalists and Calvinism is the white collar false gospel for the intellectual idiots. Righteousness by faith is the biblical understanding in the middle. Faith is the one requirement in the bible for being saved and this same faith is also spoke of as a gift. Faith is a requirement and a gift to focus on one to the exclusion of the other leads to the ditch on the right(Arminian) or the ditch on the left(Calvin).
Presumption is another wide ditch to beware of. I am not Calvinist, I read nowhere in scripture that God created the lost from the foundation of the world, I DO read that we were chosen in Christ before the foundation of the world.
The real trick is not to try to navigate between Arminius and Calvin but to believe what the bible says
..and not be a snotty nose
It was Christ who said they were of their father devil, He is a good authority. In another place he explains clearly that God sowed wheat in His field who were sons of the kingdom, and while men slept the devil came and sowed tares.
The church is still bleary eyed with sleep and cain't tell the difference between wheat and tares and who is responsible for each. "Oh" they say "no but we must love all equally, if we love hard enough the tares will anon turn into wheat, the goats will become sheep and vipers doves"
Wisdom would tell them that if an enemy hath done this then he has done it for a purpose, that is to destroy the wheat field, the kingdom.
God predestined salvation see, He did not predestine sin though He foreknew it.
...and the tares, are not in the world but right here in the church
